Arend Proof Search
Nearly every proof assistant faces a problem with poor discoverability of proven theorems. For instance, try to recall how a lemma describing the commutativity of addition is called in your favorite theorem prover. Is it add_comm
? Or +-comm
?
IntelliJ Arend provides a possibility to search for functions by the definitions they are talking about. We call this functionality Proof Search. Its closest relatives are the Search vernacular command of Coq and Type Directed Search of Idris.
Overview
Proof search can be invoked by Help
> Find Action
> Proof Search
or via the predefined hotkey Ctrl + Alt + P
(⌥ ⌘ P
on macOS).
The user interface is clear: you can just type a proof search query in the input field.
Demo of the usage:
Simply put, Proof Search shows all definitions that have a specified pattern as a subexpression of their result type.
-- The following definitions can be found by the pattern `List`:
\func foo : List Nat
\func bar : \Sigma (List Bool) Nat
\func baz {A : \Type} : List A
It is possible to specify an _
as a pattern for an arbitrary term. Also, patterns can be provided in their infix form.
-- The following definitions can be found by the pattern `_ + _ = _ + _`.
\func foo (a b : Nat) : a + b = b + a
\func bar (a b : Int) : a + b = b + a
Apart from displaying the search results, it is possible to show the definition of each entry (by pressing Enter
), navigate to the location of the selected definition (F4
), and insert the selected definition in the editor (Ctrl + Enter
/ ⌘ Enter
).
Query Language
Results of the search can be refined by specifying a restrictive query. Proof Search Queries admit the following grammar:
query ::= (and_pattern '->')* and_pattern
and_pattern ::= (app_pattern '\and')* app_pattern
app_pattern ::= atom_pattern+
atom_pattern ::= '_' | (IDENTIFIER '.')* IDENTIFIER | '(' app_pattern ')'
IntelliJ Arend provides highlighting for the queries, so syntax errors will be easily discoverable.
Parameters and result type
If there is an ->
in a query (i.e. it has several and_pattern
s), then the rightmost and_pattern
will be matched with the codomain of the definition, and the rest patterns delimited by ->
will be matched with the domain parameters of the definition.
-- The pattern is `Foo -> Bar`
\func foo (f : Foo) : Bar -- matched
\func bar : Foo -> Bar -- matched
\func baz : Bar -- rejected
The order of the left and_pattern
s is not important.
-- The pattern is `Nat -> Bool -> List Nat`
\func foo (n : Nat) (b : Bool) : List Nat -- matched
\func bar (b : Bool) (n : Nat) : List Nat -- matched
Matching multiple patterns in the same term
If there is an \and
in an and_pattern
(i.e. it has several app_pattern
s), then the term matches an and_pattern
iff it matches all its app_pattern
s at once. This is useful when you want to find a function that tells something about several definitions, but you don’t remember where they are located precisely.
-- The query is `Nat \and Bool`
\func foo : \Sigma (List Nat) Bool -- matched
\func bar : List Bool = Nat -- matched
Certainly, it is possible to use \and
in patterns for parameters:
-- The query is `Nat \and Bool -> _`
\func foo (e : \Sigma (List Nat) Bool) : 1 = 1 -- matched
There is a difference between Nat -> Bool -> _
and Nat \and Bool -> _
: the former will match all definitions that have (not necessarily distinct) parameters mentioning Nat
and Bool
, while the latter requires the existence of a parameter, that mentions Nat
and Bool
at the same time.
Restricting namespaces
An app_pattern
resembles an application of a function. It can represent a tree of a function call, where subtrees (nested applications) should be surrounded by ()
. An _
can be specified when an arbitrary term is acceptable here. It is not necessary to consider the exact arity of a function in a pattern.
\func foo (n : Nat) (m : Bool) : \Type
\func bar (n : Nat) : Nat
\func baz : Nat
-- The following matches the queries `foo (bar baz) _`,
-- `foo (bar baz)`, `foo _`, `foo`
\func f : List (foo (bar baz) true) -- matched
It is possible to specify a subsequence of a module path for the identifier. Also note, that IntelliJ Arend provides code completion for the queries.
\module Foo \where \func foo : Nat
\module Bar \where \func foo : Nat
-- The query is `foo`
\func f : Foo.foo -- matched
\func g : Bar.foo -- matched
\func h : \Sigma (Foo.foo = Bar.foo) -- matched
-- The query is `Foo.foo`
\func f : Foo.foo -- matched
\func g : Bar.foo -- rejected
\func h : \Sigma (Foo.foo = Bar.foo) -- matched
-- The query is `Foo.foo \and Bar.foo`
\func f : Foo.foo -- rejected
\func g : Bar.foo -- rejected
\func h : \Sigma (Foo.foo = Bar.foo) -- matched


Write a function that finds all the occurrences of word in a text. The search can be case sensitive or case insensitive. Use function overloading.

Y.PaginatorView Class
A View class extension to serve as a User Interface for the tracking of "pagination state" of a set of data. This PaginatorView was specifically designed to work with PaginatorModel serving as the "model" (in MVC parlance), although would work with any user-supplied model under conditions where similar attributes and attribute changes are mapped.
The PaginatorView was originally designed to function with DataTable (See Y.DataTable.Paginator) for managing the UI
and page state of paginated tables, although it isn't necessarily limited to that application. This View responds to
the model's attribute xxxxChange
events and updates the UI accordingly.
The PaginatorView utilizes an HTML template concept, where certain replaceable tokens uniquely related to this view, in addition to all of the model's attributes, can be defined for positioning within the Paginator container.
Usage
// Setup a paginator view based on a data model for 500 items, paged at 50 per page ...
var pagView = new Y.PaginatorView(
container: '#myPagDIV',
paginatorTemplate: '#script-tmpl-mypag',
model: new Y.PaginatorModel({
totalItems: 500,
itemsPerPage: 50
})
}).render();
View 'container'
The container attribute is the only REQUIRED attribute for this View, primarily because we need to know where to construct it positionally on the page.
This view has been designed such that the container
setting can be either (a) an actual Y.Node instance OR
(b) a DOM css selector ID ... assumed if the container setting is a {String} with the first character is '#'.
Paginator HTML Template
The "HTML template" for this PaginatorView is the guts of displaying the user interface. We refer to this as the "template" because it
typically contains standard HTML but also includes "replacement tokens" identified by {your token here}
curly braces.
A definition of HTML Template for the paginator can be achieved through several methods;
- Including the HTML template as content within the original
container
DOM element ... template retrived via .getHTML() - Setting the paginatorTemplate attribute to either the template 'string', or giving a SCRIPT template DOM[id] or Y.Node
- Doing neither of the above ... where the default template is used (from TMPL_PAGINATOR static property)
(Note: If for some reason it is desired to not have a "template" (because you are rendering one outside of this view), setting
paginatorTemplate:''
will override the default.)
A noteworthy component of the "HTML template" includes the token {pageLinks}
, which signifies where links generated by this
view for each page selector are to be placed. In some instances (e.g. a Paginator Bar, with an INPUT[text] for page #) you may not
desire to have every link generated ... (think of a paginator with hundreds of pages, thus hundreds of links).
A sub-template is used to generate the "{pageLinks}" content, please see attribute pageLinkTemplate for information.
For a listing of all recognized "replaceable tokens" that can be included in the template is shown on the render method API page.
Data Attribute
A key takeaway for using this View is that page links (i.e. actionable selectable elements, such as A, BUTTON, DIV, etc...) for a specific page use an HTML "data" attribute which defines the page associated with the link.
The data attribute used within the view is data-pglink
, and can have a value setting of "first", "last", "prev", "next" or any
numeric page number.
For example, the following are all valid page link identifiers;
Last
<button data-pglink="6" class="myBtn">Page 6</button>
<select><option data-pglink="19" value="19">Page 19 : Rows 9501 - 10000</option></select>
Connecting to "other" UI Elements / Widgets
This View can be restricted to situations where the use desires to construct their own unique pageLinkTemplate
and create their own
events
attribute to set listeners.
For example, the PaginatorView's render event can be listened for to ensure that the paginator has been initialized and setup.
Additionally the pageChange event (of the view) can be listened for to do any updating to user-specified page links and or a supporting YUI Widget.
Please see the examples for a guide on how to achieve this.

Attributes
Events
Methods
_bindUI
()
private
Setup listeners on this View, specifically on all UI elements and "most importantly", listen to "pageChange" on the underlying Model.
Returns:
_calcOffset
-
cpage
-
offset
Helper method to calculate offset either side of Selected Page link for abbreviated Page List.
Called by _processPageChange
Parameters:

e
Handler responding to a Page Selector "click" event. The clicked Node is reviewed for its data-pglink="" setting, and processed from that.
Changed page is then sent back to the Model, which reprocesses the
paginator settings (i.e. indices) and fires a pageChange
event.

private
Initializer sets up classes and the initial container and HTML templating for this View.
Returns:
render
()
public
Renders the current settings of the Paginator using the supplied HTML content from the for the paginator template and Y.Lang.sub for replacement of tokens and of Model attributes.
NOTE: The render method is not called on every page "click", but is called if the Model changes
totalItems
or itemsPerPage
.
Recognized tokens:
Recognizeable tokens are supported, specifically as placeholders within the html template where generated content can be inserted and ultimately rendered in the view container.
Tokens replaced within this method include all of the PaginatorModel attributes;
{page}, {totalItems}, {itemsPerPage}, {lastPage}, {totalPages}, {itemIndexStart}, {itemIndexEnd}
Additionally, specific tokens intended for view HTML construction and recognized by PaginatorView are;
- {pageLinks} : The placeholder within the html template where the View-generated page links will
be inserted via a loop over all pages (DEFAULT: see TMPL_LINK) - {inputPage} : An INPUT[type=text] box which the view listens for change events on (Default: see TMPL_inputPage)
- {selectRowsPerPage} : A SELECT type pulldown that will be populated with the pageOptions
array
of "Rows per Page" selections (Default: see TMPL_selectRPP) - {inputRowsPerPage} : An INPUT[type=text] box what will be listened to for changes to "Rows per Page" (Default: see TMPL_inputRPP)
- {selectPage} (Not implemented at this time!)
- {pageStartIndex} : Represents the starting index for a specific "page" (intended for use within pageLinkTemplate )
- {pageEndIndex} : Represents the ending index for a specific "page" (intended for use within pageLinkTemplate )
And if that wasn't enough, the CSS class names supported by this view are also provided via tokens as; {pagClass}, {pageLinkClass}, {inputPageClass}, {selectRPPClass}, {selectPageClass}, {inputRPPClass}
This method utilizes the Y.substitute tool (with recursion) for token replacement.
The container
visibility is disabled during construction and insertion of DOM elements into the container
node.
This method fires the render
event, for View listeners.
Returns:

Attributes
alwaysShowFirst
Boolean
Flag to indicate whether the first page link within the {pageLinks}
template is to be displayed or not.
Specifically intended for abbreviated page link lists (See maxPageLinks attribute).
For Example;
If our paginator state currently has 9 pages, and the current page is 5, if alwaysShowLast:false
and alwaysShowFirst:false
the link list will resemble;
First | Prev | ... 4 5 6 ... | Next | Last
Likewise, with 'alwaysShowLast:true
(and alwaysShowFirst:true) the link list will resemble;
First | Prev | 1 ... 4 5 6 ... 9 | Next | Last
Default: false
alwaysShowLast
Boolean
Flag to indicate whether the last page link within the {pageLinks}
template is to be displayed or not.
Specifically intended for abbreviated page link lists (See maxPageLinks attribute).
See alowsShowFirst
for an example.
Default: false
circular
Boolean
Flag indicating whether "circular" behavior of the Paginator View is desired. If true
the paginator
will stop "disabling" First|Previous or Next|Last toggling and will continue at either 1st page or last
page selections. (i.e. when on last page, a next click will return to page 1)
Default: false
container
Node | String
required
The container holder for the contents of this View. Can be entered either as a Y.Node instance or as a DOM "id" attribute (if prepended by "#").
Default: null
Example:
container: Y.one("#myDiv"),
OR
container: "#myDiv"
NOTE: If the container node contains HTML it will be used as the paginatorTemplate
linkListOffset
Integer
Setting that represents the number of links adjacent to the current page that should be displayed for instances where
an abbreviated page link list is desired.
(See maxPageLinks and pageLinkFiller attributes).
For example, a setting of this attribute to 1, will result in 3 page links (current page plus 1 each side),
likewise a setting of 2, will results in 5 page links in the center of the paginator, etc.
Default: 1
maxPageLinks
Integer
Used to set the maximum number of page links that will be displayed for individual pages within {pageLinks}
.
This is the primary attribute to use to setup abbreviated page links, to avoid a long line of page links
that travel across the page!
Setting this to some number less than the total number of pages will begin abbreviating the links.
(See also attributes linkListOffset
and pageLinkFiller
, which work in conjunction with this attribute).
Default: 9999
model
Y.PaginatorModel
The base PaginatorModel that serves as data / change provider for this View.
Default: null
Example:
paginator: new Y.PaginatorModel({
itemsPerPage: 250
}),
OR
paginator: myPagModel // where myPagModel is an instance previously created ...
pageLinkFiller
String
Setting the the ".. more" indicator to be used specifically for abbreviated page link lists.
(See maxPageLinks and linkListOffset attributes).
Default: '...'
pageLinkTemplate
String
Defines the HTML template to be used for each individual page within the Paginator. This can be used along
with replacement tokens to create UI elements for each page link. The template is used to construct the
{pageLinks}
replacement token with the paginator body.
Recognized replacement tokens most appropriate to this attribute are {page}
, {pageStartIndex}
and
{pageEndIndex}
.
A few examples of this template are listed below;
Default: See TMPL_LINK static property
Example:
pageLinkTemplate: '{page}'
pageOptions
Array
An array that will be used to populate the rows per page SELECT box ( using string replacement "{selectRowsPerPage}" or class selector "yui3-pagview-select-rowsperpage" ).
Default: [ 10, 20, 'All' ]
paginatorTemplate
Node | String
A string that defines the Paginator HTML contents. Can either be entered as a {String} including replacement parameters
or as a {Node} instance whose contents will be read via .getHTML() or a DOM "id" element (indicated by '#' in first character)
To disable creation of any template (in order to do your own replacements of the template), set this to ''.
Default: See TMPL_PAGINATOR static property
Example:
paginatorTemplate: '
FIRST
 {pageLinks}
LAST
',
paginatorTemplate: Y.one('#script-id-tmpl'),
paginatorTemplate: Y.one('#script-id-tmpl').getHTML(),
paginatorTemplate: '#script-id-tmpl', // where

Years of firefighting did take a toll on my feet, and nothing helped till I found the WalkFits®. They feel great. There's no pain. I kick myself for spending over $200 on those other orthotics when I could have bought 10 WalkFits® for the price of one. I've been wearing them for five years and haven't had a lick of pain ever since"

BTS Jungkook is first male idol to achieve 100m streams on Spotify
- Advertisement -
South Korean K-pop band BTS’s Jungkook hit another record to be the first male idol in a group to achieve a whopping number of 100 million streams on Spotify.
He also achieved that with an unpromoted b-side. The single, Euphoria is currently the third most streamed song by a Korean soloist on Spotify.
It is also the longest-charting song by a male idol on BB World digital song sales.
Euphoria achieved critical acclaim and is a favourite among celebrities.

The song was also played as a soundtrack on HBO’s Euphoria finale and has over one million unique listeners on the South Korean streaming platform Genie.
It is also the most successful BTS song chart-wise.
BTS, also known as Bangtan Boys is a South Korean boy band formed in Seoul in 2013.
Its members are Jin, Suga, J-Hope, RM, Jimin, V and Jungkook. The group co-writes and produces most of their material.
Born in Busan on 1 September 1997, Jungkook’s family consists of his parents and an elder brother. He studied at Baekyang Elementary and Middle School in Busan.
He transferred to Singu Middle School in Seoul when he became a trainee.
Since young, he wanted to be a badminton player but after he saw G-Dragon perform Heartbreaker on TV, it influenced him to pursue a singing career.
In 2013, he made his debut with K-pop group BTS.
In other news, K-pop boy group BTS has officially become the second-ever global artist to top the Social 50 chart in a total of 150 weeks after Justin Bieber according to Billboard on Oct 31.
This marks their 120th consecutive #1 as the group tops the Billboard Social 50 chart for the week of Oct 24.
At 163 weeks, Justin Bieber currently holds the highest number of weeks as #1 on the Social 50 chart.
Taylor Swift and Rihanna have a record of 28 weeks and 21 weeks, respectively.

Downbeat Diner & Lounge in Chinatown up for sale | Honolulu Star-Advertiser
Chinatown’s Downbeat Diner & Lounge is up for sale.
Founder Serena Hashimoto is looking for buyers for the restaurant and music venue, which has nightly entertainment by up-and-coming artists.
She retired this summer and gave the business to her daughter, Isabella, who she says no longer wants to be in the food-service industry. Hashimoto said there are three to four potential buyers, some who want to keep the concept and some who don’t.
“I’m hoping to turn it over to someone who wants to keep it Downbeat, which opened on Jan. 1, 2011,” she said. “It’s important to have that size of venue for the musical community. We have all sorts of musical acts but in particular younger bands … that are just starting out. It’s also good for big acts who want to have a more intimate show.”
The lounge has hosted “hundreds of acts,” mostly local, over the past nine years. Once in awhile, the business features traveling musicians and occasionally brings in entertainers from the mainland.
The diner seats 50 and the lounge holds around 100 people. The restaurant menu includes popular vegan dishes and milkshakes.

If using pork loin on the bone, carefully cut the meat from the bone with a sharp knife and trim away any excess fat and sinew. Cut the loin into pieces weighing about 75g/2½oz each.
 If using ready-sliced pork loin, trim off any excess fat or sinew.
Once the pork loin pieces are cut to the correct size, lay the slices between two pieces of cling film. Using a meat mallet or a rolling pin, bash them out to a thickness of about 5mm/¼in.
Place the breadcrumbs in a shallow bowl. Grate the lemon zest into the bowl with the breadcrumbs (keep the lemons for the sauce).
Add the chopped rosemary to the bowl with the breadcrumbs and lemon zest. Season, to taste, with salt and freshly ground black pepper. Mix well.
Place the flour in another shallow bowl.
Mix the milk and eggs together in a bowl.
Dredge one of the pork escalopes in the flour, then dip it in the egg wash, then coat in the breadcrumbs. Dip and coat the pork a second time, so that it's well coated with seasoned crumbs. Put on a plate while you prepare the other escalopes.
Repeat the dredging, dipping and coating process with the remaining pork pieces until all are well coated.
Heat a large frying pan over a medium heat and melt half the butter and add a drizzle of olive oil.
When the butter is foaming, add the escalopes and fry them until golden-brown, then turn them over and cook on the other side.
When they're cooked through, remove from the pan, drain on kitchen paper and keep warm.
To make the sauce, add the rest of the butter to the pan with the juice of the lemons and the wine. Turn up the heat to reduce the sauce by half.
Serve the pork escalopes with the lemon and butter sauce poured over and a green salad on the side.

--- layout: api title: "v2.1.6 JavaScript Library: Upgrading from Mapbox.js v1" categories: api version: v2.1.6 permalink: /api/v2.1.6/upgrading-from-mapbox-js-v1/ ---
In a few cases, you may need to make changes to code written for Mapbox.js 1.x versions in order to work with Mapbox.js 2.x.
Mapbox.js 2.x uses version 4 of the Mapbox web services API, which requires API access tokens. You must supply an access token to Mapbox.js; see API access tokens for details.
The markerLayer
alias has been removed from L.mapbox.map
. Use featureLayer
instead. For example, replace
map.markerLayer.setFilter(function(f) { ... });
with
map.featureLayer.setFilter(function(f) { ... });
L.mapbox.geocoder
and L.mapbox.geocoderControl
no longer accept arbitrary map IDs.
Instead you must provide a predefined geocoder index ID (or the ID of a custom geocoder
index). For instance, replace
L.mapbox.geocoderControl('examples.map-i86nkdio').addTo(map);
with
L.mapbox.geocoderControl('mapbox.places').addTo(map);
See the geocoding API documentation for a complete list of predefined geocoding indexes.
The format for L.mapbox.geocoder
and L.mapbox.geocoderControl
results have changed.
Results are now provided in GeoJSON format. If your code uses L.mapbox.geocoder
or
the found
, select
, or autoselect
events from L.mapbox.geocoderControl
, it may
need to be updated to expect the format documented in those classes.
L.mapbox.config.HTTP_URLS
and L.mapbox.config.HTTPS_URLS
have been replaced
with L.mapbox.config.HTTP_URL
and L.mapbox.config.HTTPS_URL
, which expect to
be assigned a single URL rather than an array of URLs. For example, replace
L.mapbox.config.HTTP_URLS = ["http://example.com/"];
with
L.mapbox.config.HTTP_URL = "http://example.com/";
L.mapbox.tileLayer
no longer supports detectRetina
, retinaVersion
, or autoscale
options.
Instead, retina tiles are always automatically used when available.
L.mapbox.geocoder
no longer has setURL
, setID
, and setTileJSON
methods. Instead
of resetting the URL or ID, construct a new instance with the desired URL or ID. Instead of
setting TileJSON, construct an instance from the geocoding URL in the TileJSON.

When unitize
is run with a test file against an existing unitizer
store, each test in the file is matched and compared to the corresponding test in the store. Here is a comprehensive list of possible outcomes:
unitizer
store no longer exists in the test file so you will be prompted to remove it from the store.unitizer_sect
for more details on custom comparison functions). Because the comparison function itself failed, unitizer
has no way of knowing whether the test passed or failed; you can think of it as an NA
outcome.When reviewing tests, unitizer
will group tests by test type, so you will review all new tests in one go, then the failed tests, and so on. As a result, the order that you review tests may not be the same as the order they appear in in the test file.
As noted previously simple assignments are not considered tests. They are stored in the unitizer
store, but you are not asked to review them, and their values are not compared to existing reference values prior to storage. The implicit assumption is that if there is an assignment the intent is to use the resulting object in some later test at which point any issues will crop up. Skipping assignment review saves some unnecessary user interaction.
You can force assignments to become tests by wrapping them in parentheses:
a <- my_fun(25) # this is not a test
(a <- my_fun(42)) # this is a test
The actual rule unitizer
uses to decide whether an expression is a test or not is whether it returns invisibly. Wrapping parentheses around an expression that returns invisibly makes it visible, which is why assignments in parentheses become tests. Conversely, you can wrap an expression in invisible(...)
to prevent it from being treated as a test.
unitizer
Test ComponentsThe following aspects of a unitizer tests are recorded for future comparison:
invokeRestart
(e.g. was stop
called in the expression).Currently only the first two elements are actually compared when determining whether a test passes or fails. These two should capture almost all you would care about from a unit test perspective.
Screen output is omitted from comparison because it can be caused to vary substantially by factors unrelated to source code changes (e.g. console display width). Screen output will also seem identical to the value as most of the time screen output is just the result of printing the return value of an expression. This will not be the case if the expression itself prints to stdout
explicitly, or if the function returns invisibly.
Message output is omitted because all typical mechanisms for producing stderr
output also produce conditions with messages embedded, so it is usually superfluous to compare them. One exception would be if an expression cat
ed to stderr
directly.
The “abort” invokeRestart
is omitted because it generally is implied by the presence of an error condition and actively monitoring it clutters the diagnostic messaging produced by unitizer
. It exists because it is possible to signal a “stop” condition without actually triggering the “abort” restart so in some cases it could come in handy.
While we omit the last three components from comparison, this is just default behavior. You can change this by using the compare
argument for unitizer_sect
.
untizer_sect
Often it is useful to group tests in sections for the sake of documentation and clarity. Here is a slghtly modified version of the original demo file with sections:
unitizer_sect("Basic Tests", {
library(unitizer.fastlm)
x <- 1:10
y <- x ^ 3
res <- fastlm(x, y)
get_slope(res)
})
unitizer_sect("Advanced Tests", {
2 * get_slope(res) + get_intercept(res)
get_rsq(res)
})
Now re-running unitizer
segments everything by section (note, first few lines are set-up):
(.unitizer.fastlm <- copy_fastlm_to_tmpdir())
update_fastlm(.unitizer.fastlm, version="0.1.2")
install.packages(.unitizer.fastlm, repos=NULL, type='src', quiet=TRUE)
unitize(file.path(.unitizer.fastlm, "tests", "unitizer", "unitizer.fastlm.R"))
+------------------------------------------------------------------------------+
| unitizer for: tests/unitizer/unitizer.fastlm.R |
+------------------------------------------------------------------------------+
Pass Fail New
1. Basic Tests - - 1
2. Advanced Tests - - 2
..................................
- - 3
If there are tests that require reviewing, each section will be reviewed in turn.
Note that unitizer_sect
does not create separate evaluation environments for each section. Any created object will be available to all lexically subsequent tests, regardless of whether they are in the same section or not. Additionally on.exit
expressions in unitizer_sect
are evaluated immediately, not on exit.
It is possible to have nested sections, though at this point in time unitizer
only explicitly reports information at the outermost section level.
By default tested components (values and conditions) are compared with all.eq
, a wrapper around all.equal
that returns FALSE on inequality instead of a character description of the inequality. If you want to override the function used for value comparisons it is as simple as creating a new section for the tests you want to compare differently and use the compare
argument:
unitizer_sect("Accessor Functions", compare=identical,
{
get_slope(res)
get_rsq(res)
get_intercept(res)
} )
The values produced by these three tests will be compared using identical
instead of all.eq
. If you want to modify how other components of the test are compared, then you can pass a unitizerItemTestsFuns
object as the value to the compare
argument instead of a function:
unitizer_sect("Accessor Functions",
compare=unitizerItemTestsFuns(
value=identical,
output=all.equal,
message=identical
),
{
get_slope(res)
get_rsq(res)
get_intercept(res)
} )
This will cause the value of tests to be compared with identical
, the screen output with all.equal
, and messages (stderr) with identical
.
If you want to change the comparison function for conditions, keep in mind that what you are comparing are conditionList
objects so this is not straightforward (see getMethod("all.equal", "conditionList")
). In the future we might expose a better interface for custom comparison functions for conditions (see issue #32).
If you need to have different comparison functions within a section, use nested sections. While unitizer
will only report the outermost section metrics in top-level summaries, the specified comparison functions will be used for each nested section.
source
When unitizer
runs the test expressions in a test file it does more than just evaluating each in sequence. As a result there are some slight differences in semantics relative to using source
. We discuss the most obvious ones here.
on.exit
Each top-level statement statement, or top-level statement within a unitizer_sect
(e.g. anything considered a test), is evaluated directly with eval
in its own environment. This means any on.exit
expressions will be executed when the top-level expression that defines them is done executing. For example, it is not possible to set an on.exit(...)
for an entire unitizer_sect()
block, although it is possible to set it for a single sub-expression:
unitizer_sect('on.exit example', {
d <- c <- b <- 1
on.exit(b <- 2)
b # == 2!
{
on.exit(d <- c <- 3)
c # Still 1
}
d # == 3
}
Each test is evaluated in its own environment, which has for enclosure the environment of the prior test. This means that a test has access to all the objects created/used by earlier tests, but not objects created/used by subsequent tests. See the Reproducible Tests Vignette for more details.
In order to properly capture output, unitizer
will modify streams and options. In particular, it will do the following:
options(warn>=1L)
during expression evaluation.options(error=NULL)
during expression evaluation.sink()
to capture any output to stdout
.sink(type="message")
to capture output to stderr
.This should all be transparent to the user, unless the user is also attempting to modify these settings in the test expressions. The problematic interaction are around the options
function. If the user sets options(warn=1)
with the hopes that setting will persist beyond the execution of the test scripts, that will not happen. If the user sets options(error=recover)
or some such in a test expression, and that expression throws an error, you will be thrown into recovery mode with no visibility of stderr
or stdout
, which will make for pretty challenging debugging. Similarly, unitize
ing debug
ged functions, or interactive functions, is unlikely to work well.
You should be able to use options(warn=2)
and options(error=recover)
from the interactive unitizer
prompt.
If unitize
is run with sdtderr
or stdout
sunk, then it will subvert the sink during test evaluation and reset it to the same sinks on exit. If a test expression sinks either stream, unitizer
will stop capturing output from that point on until the end of the test file. At that point, it will attempt to reset the sinks to what they were when unitizer
started. Sometimes this is not actually possible. If such a situation occurs, unitizer
will release all sinks to try to avoid a situation where control is returned to the user with output streams still captured.
To reduce the odds of storing massive and mostly useless stdout
, unitize
limits how much output is stored by default. If you exceed the limit you will be warned. You may modify this setting with options("unitizer.max.capture.chars")
.
Whenever you re-run unitize
on a file that has already been unitize
d, unitizer
matches the expressions in that file to those stored in the corresponding unitizer
store. unitizer
matches only on the deparsed expression, and does not care at all where in the file the expression occurs. If multiple identical expressions exist in a file they will be matched in the order they show up.
The unitizer_sect
in which a test was when it was first unitize
d has no bearing whatsoever on matching a new test to a reference test. For example, if a particular test was in “Section A” when it was first unitize
d, but in the current version of the test file it is in “Section X”, that test will be matched to the current one in “Section X”.
Some expressions may deparse differently on different systems (e.g. numbers with decimal places, non-ASCII characters) so tests containing them may not match correctly across systems. See the Introductory Vignette for how to avoid problems with this.
unitizer
parses the comments in the test files and attaches them to the test that they document. Comments are attached to tests if they are on the same line as the test, or in the lines between a test and the previous test. Comments are displayed with the test expression during the interactive review mode. Comment parsing is done on a “best-efforts” basis; it may miss some comments, or even fail to work entirely.

Description
The main goal of the article is to present the results of a study on the use of deep learning networks to detect solar panels based on aerial images of Poznan. In addition, the main motivation is to obtain more detailed information about the use of solar energy in Poland drawing on big data sources, which until now have not been used for this purpose.
The data was acquired from the Management Board of Geodesy and Municipal Cadastre GEOPOZ in Poznań and included orthophotomaps for 2016 and the layer of buildings and plots of lands. We extracted buildings from the images using R statistical software and the sf package. To detect solar panels we used the Turi Create library written in Python which re-implements the YOLO (You Only Look Once) library.
The object recognition algorithm was trained on a sample of images that included annotations (bounding boxes) about the exact location of solar panels. The results indicate a very high recognition efficiency at the level of 96-99% on the test sample. Based on this procedure we found that around 2% of residential buildings in Poznań in 2016 had solar panels mounted on roofs.
As far as we know, this is the first use of deep learning to detect solar panels in Poland. Currently, similar studies are being carried out by for instance Statistics Netherlands as part of the DeepSolaris project. The study exemplifies a trend involving the use of aerial and satellite images for statistical purposes thanks to advanced machine learning algorithms and open source software.

GUI.CreateButtonFull (x, y, width : int, text : string,
actionProc : procedure x (), height : int, shortcut : char, default : boolean) : int
The button widget is used to implement a textual button. When you click on a button, the button's action procedure is called. If a button is given a short cut, then entering the keystroke will cause the action procedure to be called. It will not visibly cause the button to depress.
The x and y parameters specify the lower-left corner of the button. The width parameter specifies the width of the button. If width is less than the size necessary to display the button, the button is automatically enlarged to fit the text. The text parameter specifies the text to appear in the button. The actionProc parameter is the name of a procedure that is called when the button is pressed.
For GUI.CreateButtonFull, the height parameter specifies the height of the button. If height is less than the size necessary to display the button, the button is automatically enlarged to fit the text. The shortcut parameter is the keystroke to be used as the button's shortcut. The default parameter is a boolean indicating whether the button should be the default button. If there is already a default button, and default is set to true, then this button becomes the new default button.
import GUI
procedure DrawRandomCircle
var r : int := Rand.Int (20, 50)
var x : int := Rand.Int (r, maxx - r)
var y : int := Rand.Int (r, maxy - r)
var c : int := Rand.Int (0, maxcolor)
Draw.FillOval (x, y, r, r, c)
% In case we drew over the buttons, redraw them.
GUI.Refresh
end DrawRandomCircle
View.Set ("graphics:300;200,nobuttonbar ")
var draw : int := GUI.CreateButtonFull (50, 10, 0, "Draw Circle",
DrawRandomCircle, 0, '^D', true)
var quitBtn : int := GUI.CreateButton (200, 10, 0, "Quit", GUI.Quit)
loop
exit when GUI.ProcessEvent
end loop
If a button's width or height is set to zero (or not specified at all), then the button is shaped to fit the text.
A button can be the default button for a window. The default button is drawn with a thicker border around it. If the user presses ENTER in a window with a default button, the default button's action procedure is called.
When a button is not enabled, the text in the button is grayed out and the button no longer responds to any mouse clicks or keystrokes until the button is enabled again.
| GUI.Show, GUI.Hide, GUI.Enable, GUI.Disable, GUI.Dispose, GUI.GetX, GUI.GetY, GUI.GetWidth, GUI.GetHeight, GUI.SetPosition, GUI.SetSize, GUI.SetPositionAndSize, GUI.SetLabel, GUI.SetDefault |
This means that you can only call the function by calling GUI.CreateButton, not by calling CreateButton.


My resumé says that I have an MBA, I acted as country manager, marketing manager, business developer, head of operations, and so on. But when you come down to it, I’m much more :)
I’m an entrepreneur: I would say that all companies that I have worked in were in an initial stage even the global ones. The American UCI Cinemas, the Italian TIM Telecom, the Danish Atchik-Realtime, The Brazilians LGR, and Edi, all of them independent of budgets and size, were in a startup phase. I was born to manage areas and companies in this mood!.
A Digital Marketing and Social media strategist: The first time I have seen a social media community was in 2003 in blah! , a global brand from TIM. Since then I managed more than 10 social media communities branded by Telecom companies and Atchik-Realtime: blah!, Oi Pegação, Claro Chat, Entel Chat among others. More than 20 million active users and all the crazy KPIs and engagement strategies to make it happen for years.
A geek-marketer: I love data, design, and innovative thinking. I did an MBA in Marketing and Innovation. For me, Marketing is precise information and good-sense with a spark of innovation. Ask me anything about bots, AI, Python, Pandas(not the animals), and even machine learning models applied to boost engagement, sales, test marketing campaigns, and provide predictions. I can spend hours talking about that! Seriously!
I’m also a big believer in people. I have managed several teams in different cultures and organizational models. From the traditional project management to Agile approach, I come across very smart people from LATAM, Africa, Europe, and Asia. A mix of cultures and behavior, motivations, and expectations. It was great and challenging managing so many diversity. Maybe what I most miss in all companies I have worked before.
Head of Digital Transformation and operations
Head of Digital Transformation and Operations
Edi. Digital - Service provider based on Machine Learning, chatbot platforms, and IoT solutions. I work with various teams to successfully map, design, launch, commercialize, and scale the digital process to clients. I translate the customer needs into business and design technical requirements for the best digital solution. In six months of commercialization, Edi achieved significant customers in Brazil such as telecom operators, shopping malls, and security companies.
Country Manager in Brazil, Chile and Mexico
Country Manager in Brazil, Chile and Mexico
Atchik-Realtime is a danish multinational company of technology and mobile marketing Head of the Brazilian subsidiary from 2005 to 2007. Head of the Brazilian and Chilean operations from 2008-2017. I accelerated the growth of the Atchik-Realtime in Brazil and Chile. Planned with the company's board, its corporate objectives. I have designed the marketing, sales, and IT areas. I managed teams in Brazil, Chile, Mexico, and Denmark. I have negotiated strategic contracts with management and C-levels executives from companies such as Oi, Claro in Latam, TIM, and Entel Chile. During the time I run Atchik, clients achieved a loyal customer base and some of them with more than one million active users/month. I have managed several projects ('waterfalls' and 'agile') to launch new products and features together with teams from different countries.
SVA Marketing and Content Manager LATAM
SVA Marketing and Content manager LATAM
I have led the creation of the world's first mobile carrier branding store - blah!loc - with design offices Ana Couto e Tátil, Bel Lobo architecture, and partners such as Nokia. The branding store was responsible for the user experience with the brand as well as being a UX lab for new products and usability. I have improved the access to the company's digital products by negotiating points of sale in vending machines and large retail chains through prepaid cards. I have also increased TIM's product offers by negotiating new content agreements with various media, music, and game companies like Sony Music, Globo.com, EA, and Gameloft..
Head of Retail Brazil
Head of Retail Brazil
American multinational company of entertainment and multiplex cinemas Head of the Retail area in Brazil that included sales, supply chain process, logistics, purchasing, sales promotion, and management of all franchising and food stores inside the complexes. Head of a team with over 150 people in 10 states of the country. Responsible for all trade marketing, sales promotion, and merchandising activities for the Food and Beverages (F&B) area.I have negotiated strategic agreements including marketing funds with major suppliers such as Coca-Cola and Warner Bros enabling promotional actions across the chain in Brazil. For three consecutive years, I achieved a 20% increase in net revenues, representing 50% of the total enterprise revenues. In partnership with Coca-Cola, I have implemented a corporate education project and business action plan for the entire operating team, achieving high levels in the business and service metrics established by the company's board.

Author: Jan Vanhove (@, www)
Last update: 12 September 2018
The accompanying article can be downloaded from PsyArxiv.
I'll assume you have some basic knowledge of R (R Core Team, 2018), such as how you can read in CSV files. In addition, if you haven't already, install and load the tidyverse suite (Wickham, 2017):
install.packages("tidyverse")
library(tidyverse)
# install the devtools package if needed: # install.packages("devtools") library(devtools) install_github("janhove/cannonball")
library(cannonball)
# Set random seed set.seed(42)
# Change default plotting theme (just my preference) theme_set(theme_bw(10))
Download the data for DeKeyser et al.'s (2010) Israel study from my website to your R working directory. (Use "save link as" for this; don't open the file in Excel and then save it. Excel has a way of messing up CSV files.) Then read it in and refit Vanhove's (2013) linear model:
# Read in data d <- read.csv("dekeyser2010.csv") # Fit linear model m <- lm(GJT ~ AOA, data = d) summary(m)
## ## Call: ## lm(formula = GJT ~ AOA, data = d) ## ## Residuals: ## Min 1Q Median 3Q Max ## -55.380 -7.338 2.662 9.777 36.204 ## ## Coefficients: ## Estimate Std. Error t value Pr(>|t|) ## (Intercept) 187.1297 4.2762 43.76 < 2e-16 *** ## AOA -1.2292 0.1226 -10.02 1.96e-14 *** ## --- ## Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1 ## ## Residual standard error: 16.23 on 60 degrees of freedom ## Multiple R-squared: 0.626, Adjusted R-squared: 0.6198 ## F-statistic: 100.4 on 1 and 60 DF, p-value: 1.965e-14
The function for generating a line-up of 19 simulated datasets alongside the real dataset is parade(). You need to supply to it the name of a fitted model; in this case m.
# Generate the parade and store it to a separate object my_parade <- parade(m)
By default, parade() generates a tibble (the tidyverse version of a data frame) with the model's predictor and outcome variables as well as its fitted values and residuals (and transformations thereof):
head(my_parade)
## # A tibble: 6 x 7 ## AOA GJT .fitted .resid .abs_resid .sqrt_abs_resid .sample ## <int> <dbl> <dbl> <dbl> <dbl> <dbl> <int> ## 1 4 204 186 18.9 18.9 4.35 1 ## 2 5 172 184 -12.3 12.3 3.51 1 ## 3 6 186 183 2.86 2.86 1.69 1 ## 4 6 190 183 7.24 7.24 2.69 1 ## 5 7 185 181 3.67 3.67 1.92 1 ## 6 7 177 181 - 4.62 4.62 2.15 1
If your dataset contains variables that weren't part of the model and you wish to include these in the line-up, supply your dataset as the input to the optional full_data parameter:
# my_parade <- parade(m, full_data = d)
Currently, parade() accepts models fitted with lm() as well as models fitted with the gam() function from the mgcv package (Wood, 2018). If there's sufficient demand (i.e., once I need it myself), other models may follow.
To check for residual patterns due to unmodelled nonlinearities, you can plot the residual values (.resid) against the fitted values (.fitted). The ggplot() call for this is:
ggplot(my_parade, # name of the parade object aes(x = .fitted, # fitted values on x-axis y = .resid)) + # residual values on y-axis geom_point(shape = 1) + # plot them as hollow points geom_smooth() + # add a nonlinear scatterplot smoother facet_wrap(~ .sample)
A quicker way to draw the same plot is to use cannonball's lin_plot() function:
lin_plot(my_parade)
Once you've made your mind up about which plot evinces the strongest pattern, reveal the true data's position using reveal():
reveal(my_parade)
# Generate a new parade my_parade <- parade(m) ggplot(my_parade, aes(x = .fitted, y = .abs_resid)) + # use .sqrt_abs_resid if you prefer # to plot the square roots of the # residuals' absolute values geom_point(shape = 1) + geom_smooth() + facet_wrap(~ .sample)
You can also use the var_plot() function if you don't want to tinker with these graphs.
var_plot(my_parade)
reveal(my_parade)
Take Five is the instantly recognisable jazz hit penned by Paul Desmond.
Depending on what you find easiest to read, you can plot the residuals in a histogram or in a quantile–quantile plot.
# New line-up my_parade <- parade(m) # Histogram ggplot(my_parade, aes(x = .resid)) + geom_histogram(bins = 30, # you can change this if you want fill = "lightgrey", colour = "black") + facet_wrap(~ .sample)
# Quantile-quantile plot ggplot(my_parade, aes(sample = .resid)) + stat_qq(shape = 1) + facet_wrap(~ .sample)
Short-hand functions to draw these graphs are:
norm_hist(my_parade)
norm_qq(my_parade)
reveal(my_parade)
This is similar to what is known as posterior predictive checking in Bayesian statistics. The idea is that you check if the model occasionally generates data that are simply impossible given what you know about the subject-matter. Here I draw 19 additional scatterplots of the (simulated) AOA–GJT relationship.
# New line-up my_parade <- parade(m) ggplot(my_parade, aes(x = AOA, y = GJT)) + geom_point(shape = 1) + geom_smooth() + facet_wrap(~ .sample)
The model sometimes generates GJT data outside of the possible range (0 to 204), showing that we know something about these data that the model doesn't. In principle, we could embed this knowledge in a more complex model, but doing so is beyond the scope of this tutorial.
I cleaned up Lee et al.'s (2018) data set so that it's easier to read it into R. With their consent, I've put it on my website from where you can download it to your working directory. (Use "save link as"; don't open it in Excel and then save it.) Then read in the dataset:
# Read in data d <- read.csv("lee2018_s2.csv")
If you analysed your data using a Student's t-test and you want to use the parade() function, you need to refit the test as a linear model. This is pretty easy. Let's say your outcome variable is creatively named Y, your predictor (group) variable is called X and both are in a dataset called my_data. To run the t-test, you'd use this command:
# generic example t.test(Y ~ X, data = my_data, var.equal = TRUE)
You will obtain the same results if you use the lm() function instead:
# generic example my_model <- lm(Y ~ X, data = my_data) summary(my_model)
Similarly, an ANOVA or ANCOVA can be reproduced as a linear model. If you have more than one predictor, just add the different predictors to the model using '+'. If your ANOVA contains an interaction, use '*' between the interacting predictors:
# Fit linear model m <- lm(Happiness ~ PurchaseType * SocialClass, data = d) summary(m)
## ## Call: ## lm(formula = Happiness ~ PurchaseType * SocialClass, data = d) ## ## Residuals: ## Min 1Q Median 3Q Max ## -5.4671 -0.3793 0.5329 0.6207 0.8385 ## ## Coefficients: ## Estimate Std. Error t value Pr(>|t|) ## (Intercept) 6.16154 0.08492 72.556 < 2e-16 ## PurchaseTypematerial 0.21777 0.12367 1.761 0.07890 ## SocialClasslow 0.30557 0.11567 2.642 0.00853 ## PurchaseTypematerial:SocialClasslow -0.37502 0.18619 -2.014 0.04456 ## ## (Intercept) *** ## PurchaseTypematerial . ## SocialClasslow ** ## PurchaseTypematerial:SocialClasslow * ## --- ## Signif. codes: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1 ## ## Residual standard error: 0.9682 on 465 degrees of freedom ## Multiple R-squared: 0.01544, Adjusted R-squared: 0.009085 ## F-statistic: 2.43 on 3 and 465 DF, p-value: 0.06457
If we check for constant variance in the same way as before, it's ridiculously easy to spot the actual data plot:
my_parade <- parade(m) ggplot(my_parade, aes(x = .fitted, y = .abs_resid)) + geom_point(shape = 1) + # geom_smooth() + # uncomment this line if you like warnings facet_wrap(~ .sample)
As discussed in the accompanying paper, I suggest to instead compute the variance or standard deviation of the residuals per cell, so that we don't confuse one clear deficiency of the model (not taking into account the categorical nature of the outcome) with another possible one (heteroskedasticity). The parade_summary() function makes it easier to compute measures. It takes as its input an object generated by the parade() function:
my_parade <- parade(m) my_parade_summary <- parade_summary(my_parade)
For each cell, parade_summary() computes the mean residual (.mean_resid), the mean absolute residual (.mean_abs_resid), the mean of the square roots of the absolute residuals (.mean_sqrt_abs_resid), the standard deviation of the residuals (.sd), the variance of the residuals (.var), and the cell size (.n). It also labels each unique combination of non-outcome variables (.cell). The mean residual per cell may be useful to check if there are any interaction patterns or predictors that still need to be accounted for; the other measures are useful for checking for non-constant variance.
head(my_parade_summary)

By default, the cells are defined as the unique combinations of all non-outcome variable values present in the parade object, even those that weren't used for fitting the model. If you only want to define the cells using the predictors actually used in the model, specify the predictors_only parameter appropriately:
# my_parade_summary <- parade_summary(my_parade, predictors_only = TRUE)
Incidentally, parade_summary() will throw a bunch of warnings if it's used in cases where I don't think that doing so is too useful (e.g., fairly continuous outcome data, non-categorical predictors, small cell sizes).
The output of parade_summary() can also be plotted using ggplot():
ggplot(my_parade_summary, aes(x = .cell, y = .sd, group = 1)) + geom_point() + geom_line() + facet_wrap(~ .sample)
You can also use the var_plot() function to draw this plot:
var_plot(my_parade_summary)
reveal(my_parade_summary)
Hey Nineteen is one of my favourite Steely Dan tracks.
Regardless of whether the residuals are displayed in a histogram or in a QQ plot, the actual data panel sticks out.
my_parade <- parade(m) norm_hist(my_parade)
norm_qq(my_parade)
If the amount of data doesn't fully reassure you, you can construct the confidence intervals using a nonparametric bootstrap. The confidence intervals are pretty much the same as those constructed using t-distributions, which technically require normality. That said, it may be a good idea to fit these data in an ordinal regression model (done but not shown here; Lee et al.'s (2018) substantive conclusions don't change).
# Check results with bootstrap ----- # Empty matrix that'll contain the bootstrap # estimates for the model's 4 coefficients. bs_est <- matrix(ncol = length(coef(m)), nrow = 20000) for (i in 1:20000) { # Draw bootstrap sample.


The outcome of this study will be the first diabetic ketoacidosis (DKA) event that occurred after the index date of an AHA therapy.
- [DKA (IP or ER)]: The primary DKA definition will identify cases from a diagnosis code recorded in inpatient or emergency room claims.
- [DKA (IP)]: A modified DKA definition will identify cases from a diagnosis code recorded in inpatient claims only.

Welcome to my website. If you want to know a little bit more about me, you've come to the right place
I'm a fun-loving, red-headed little devil who loves math and hates hapiness
, or at least that's what
the admissions councelor at the University of Utah told me.
The presence of fellow humans stresses me out, to no end, which I'm blaming on my social anxiety, but I love you all anyway!
I always want new friends, so please come give me platonic affection. Thank's in advance, and have fun with this little site!
