6 R programming
This chapter teaches you the R skills that are needed to pass PA.
6.1 Notebook chunks
On the Exam, you will start with an .Rmd (R Markdown) template, which organize code into R Notebooks. Within each notebook, code is organized into chunks.
# This is a chunk
Your time is valuable. Throughout this book, I will include useful keyboard shortcuts.
Shortcut: To run everything in a chunk quickly, press CTRL + SHIFT + ENTER
. To create a new chunk, use CTRL + ALT + I
.
6.2 Basic operations
The usual math operations apply.
# Addition
1 + 2
## [1] 3
3 - 2
## [1] 1
# Multiplication
2 * 2
## [1] 4
# Division
4 / 2
## [1] 2
# Exponentiation
2^3
## [1] 8
There are two assignment operators: =
and <-
. The latter is preferred because
it is specific to assigning a variable to a value. The =
operator is also used
for specifying arguments in functions (see the functions section).
Shortcut: ALT + -
creates a <-
..
# Variable assignment
<- 2
y
# Equality
4 == 2
## [1] FALSE
5 == 5
## [1] TRUE
3.14 > 3
## [1] TRUE
3.14 >= 3
## [1] TRUE
Vectors can be added just like numbers. The c
stands for “concatenate,” which
creates vectors.
<- c(1, 2)
x <- c(3, 4)
y + y x
## [1] 4 6
* y x
## [1] 3 8
<- x + y
z ^2 z
## [1] 16 36
/ 2 z
## [1] 2 3
+ 3 z
## [1] 7 9
I already mentioned numeric
types. There are also character
(string) types,
factor
types, and boolean
types.
<- "The"
character <- c("The", "Quick") character_vector
Character vectors can be combined with the paste()
function.
<- "The"
a <- "Quick"
b <- "Brown"
c <- "Fox"
d paste(a, b, c, d)
## [1] "The Quick Brown Fox"
Factors look like character vectors but can only contain a finite number of predefined values.
The below factor has only one “level,” which is the list of assigned values.
<- as.factor(character)
factor levels(factor)
## [1] "The"
The levels of a factor are by default in R in alphabetical order (Q comes alphabetically before T).
<- as.factor(character_vector)
factor_vector levels(factor_vector)
## [1] "Quick" "The"
In building linear models, the order of the factors matters. In GLMs, the “reference level” or “base level” should always be the level which has the most observations. This will be covered in the section on linear models.
Booleans are just TRUE
and FALSE
values. R understands T
or TRUE
in the
same way, but the latter is preferred. When doing math, bools are converted to
0/1 values where 1 is equivalent to TRUE and 0 FALSE.
<- TRUE
bool_true <- FALSE
bool_false * bool_false bool_true
## [1] 0
Booleans are automatically converted into 0/1 values when there is a math operation.
+ 1 bool_true
## [1] 2
Vectors work in the same way.
<- c(TRUE, TRUE, FALSE)
bool_vect sum(bool_vect)
## [1] 2
Vectors are indexed using [
. If you are only extracting a single element, you
should use [[
for clarity.
<- c("a", "b", "c")
abc 1]] abc[[
## [1] "a"
2]] abc[[
## [1] "b"
c(1, 3)] abc[
## [1] "a" "c"
c(1, 2)] abc[
## [1] "a" "b"
-2] abc[
## [1] "a" "c"
-c(2, 3)] abc[
## [1] "a"
6.3 Lists
Lists are vectors that can hold mixed object types.
<- list(TRUE, "Character", 3.14)
my_list my_list
## [[1]]
## [1] TRUE
##
## [[2]]
## [1] "Character"
##
## [[3]]
## [1] 3.14
Lists can be named.
<- list(bool = TRUE, character = "character", numeric = 3.14)
my_list my_list
## $bool
## [1] TRUE
##
## $character
## [1] "character"
##
## $numeric
## [1] 3.14
The $
operator indexes lists.
$numeric my_list
## [1] 3.14
$numeric + 5 my_list
## [1] 8.14
Lists can also be indexed using [[
.
1]] my_list[[
## [1] TRUE
2]] my_list[[
## [1] "character"
Lists can contain vectors, other lists, and any other object.
<- list(vector = c(1, 2, 3),
everything character = c("a", "b", "c"),
list = my_list)
everything
## $vector
## [1] 1 2 3
##
## $character
## [1] "a" "b" "c"
##
## $list
## $list$bool
## [1] TRUE
##
## $list$character
## [1] "character"
##
## $list$numeric
## [1] 3.14
To find out the type of an object, use class
or str
or summary
.
class(x)
## [1] "numeric"
class(everything)
## [1] "list"
str(everything)
## List of 3
## $ vector : num [1:3] 1 2 3
## $ character: chr [1:3] "a" "b" "c"
## $ list :List of 3
## ..$ bool : logi TRUE
## ..$ character: chr "character"
## ..$ numeric : num 3.14
summary(everything)
## Length Class Mode
## vector 3 -none- numeric
## character 3 -none- character
## list 3 -none- list
6.4 Functions
You only need to understand the very basics of functions. The big picture is that understanding functions help you to understand everything in R, since R is a functional programming language, unlike Python, C, VBA, Java, all object-oriented, or SQL, which is not a language but a series of set-operations.
Functions do things. The convention is to name a function as a verb. The function make_rainbows()
would create a rainbow. The function summarise_vectors()
would summarise vectors. Functions may or may not have an input and output.
If you need to do something in R, there is a high probability that someone has already written a function to do it. That being said, creating simple functions is quite helpful.
Here is an example that has a side effect of printing the input:
<- function(my_name){
greet_me print(paste0("Hello, ", my_name))
}
greet_me("Future Actuary")
## [1] "Hello, Future Actuary"
A function that returns something
When returning the last evaluated expression, the return
statement is optional. In fact, it is discouraged by convention.
<- function(x, y) {
add_together + y
x
}
add_together(2, 5)
## [1] 7
<- function(x, y) {
add_together # Works, but bad practice
return(x + y)
}
add_together(2, 5)
## [1] 7
Binary operations in R are vectorized. In other words, they are applied element-wise.
<- c(1, 2, 3)
x_vector <- c(4, 5, 6)
y_vector add_together(x_vector, y_vector)
## [1] 5 7 9
Many functions in R actually return lists! This is why R objects can be indexed with dollar sign.
library(ExamPAData)
<- lm(charges ~ age, data = health_insurance)
model $coefficients model
## (Intercept) age
## 3165.8850 257.7226
Here’s a function that returns a list.
<- function(x,y) {
sum_multiply <- x + y
sum <- x * y
product list("Sum" = sum, "Product" = product)
}
<- sum_multiply(2, 3)
result $Sum result
## [1] 5
$Product result
## [1] 6
6.5 Data frames
You can think of a data frame as a table that is implemented as a list of vectors.
<- data.frame(
df age = c(25, 35),
has_fsa = c(FALSE, TRUE)
) df
## age has_fsa
## 1 25 FALSE
## 2 35 TRUE
To index columns in a data frame, the same “$” is used as indexing a list.
$age df
## [1] 25 35
To find the number of rows and columns, use dim
.
dim(df)
## [1] 2 2
To find a summary, use summary
summary(df)
## age has_fsa
## Min. :25.0 Mode :logical
## 1st Qu.:27.5 FALSE:1
## Median :30.0 TRUE :1
## Mean :30.0
## 3rd Qu.:32.5
## Max. :35.0


BY EDWIN JAHIEL
THE ACCOMPANIST (L'ACCOMPAGNATRICE) (France, 1992) *** 1/2 Directed by Claude Miller. Written by Miller and luc Beraud, based on the novel by Nina Berberova. Photography, Yves Angelo. Music, Alain Jomy. Editing, Albert Jurgenson. Cast: Romane Bohringer, Elena Safonova, Richard Bohringer, Samuel Labarthe, Julien Rassam, Nelly Borgeaud, Claude Rich, et al. A Sony Classics release. 110 minutes. In French with subtitles. Rated PG.
Nazi-occupied Paris. Glamorous soprano Irene Brice (Leningrad-born, ex-Russian actress Elena Safonova) hires an accompanist. She is 20-year old Sophie (Romane Bohringer) a talented pianist who, like many French people in the winter of 1942-43, is undernourished.
Unlike many in German-dominated France, Irene and her businessman-profiteer husband Charles (Richard Bohringer, in real life Romane's father) live in luxury. Irene laughingly admits that she is isolated from "rigors and privations." The Brices hobnob with the rich and the infamous and, marginally, with the German authorities. Marginally because Charles, though an opportunist, unlike many other Frenchmen is no true collaborationist but a complex man who does a balancing act between his conscience and his self-interest. He even taunts the Germans.
Irene, a charmer, is blithely unaware of anything except music, adulation, joie de vivre and her lover Jacques. Yet she's no air head. Solemn Sophie is fairly complex. She moves in with the couple, shares some of their privileges , quietly observes their private and public lives. Her new condition does not change her much. What does affect her is her ambivalence toward Irene : a mixture of admiration and silent disapproval, and an understandable , professional frustration at staying in Irene's musical shadow. Even though she is appreciated by Irene and the public, the young pianist always remains an anonymous second fiddle to the singer. It does not help either that, in a friendly way, Irene also treats Sophie a bit like a favorite servant. And neither woman opens up to the other.
As Charles becomes increasingly conscious of reaching a kind of point of no return -- moral as well as practical-- he decides to escape from France with his wife. Taking Sophie along, they go South, cross the Pyrenees, reach Lisbon and take a freighter to England. There, the entrepreneurial Charles successfully becomes his wife's impresario -- but there is a problem: Jacques, the lover and a member of the French Underground is also in London...
The film starts out as a series of portraits and adds vivid components of life, society and dealings under the Occupation. It eventually becomes something of a saga and a melodrama, but both are played down. There is a delicate, constant balance among the three main characters. Stresses vary without becoming systematic. Although Charles may have less screen time than the women, his role keeps growing in importance and depth. It is Charles who touches you most, yet the film does not resort to simplifications, moral judgments, villains or heroes.
I said "three characters." I really meant four, the fourth one being the music. There is for me something most appealing in the way so many French films since 1960 incorporate classical music, use it organically, and often make it the key element. Think of "Diva, " "The Music Teacher," "Tous les Matins du Monde." It is a far cry from Hollywood's stubborn resistance to "serious" music, and, in quality and variety, also a far cry from the made-to-order compositions in "The Piano," an excellent film but with a jarringly anachronistic score.
Strongly and intelligently woven into the story, the mostly vocal music of "The Accompanist" ( Mozart, Schumann, Richard Strauss, Schubert, Berlioz, etc.) is not limited to snippets. Beautifully dubbed by young soprano Laurence Monteyrol, it is superbly lip-face-and-body-synched by Ms. Safonova.
The film reproduces its period with great accuracy, captures perfectly in look and content facts, situations, politics and moods of Occupied France and of Marshall Petain's Vichy Government. Vichy itself, the provincial spa that became the bizarre seat of the pro-German French State ( France's Non-Occupied Zone), comes in for some deft descriptions.
Among the best touches is a cameo by Claude Rich as a realistic, disenchanted Vichy Minister who lends a sympathetic ear to Charles' determination to escape. References to Petain, Laval, Brinon, Otto Abetz, Doriot, the Free French, De Gaulle and the like add much to the ambiance if you know this particular chapter in history.
There are many subtleties, such as color differences between the French sequences and those of wartime London, the latter, says director Miller, shot "with deep reds and blacks, like old Rank films. " And there is at least one conceit, included, no doubt, for the delectation of movie specialists: Charles, near the end, tells his wife: "I hate the character that you are making me play." This is almost word for word what another Charles, actor Charles Boyer, said to his wife in Max Ophuls' 1953 gem "The Earrings of Madame de..."
I tip my hat to a movie that does not try to simplify people, issues and facts, and works in music so effectively. Even if viewers do not identify every historical detail, the film is not at all hard to follow. My only puzzlement is why Jacques always sports a heavy five o'clock shadow,
Claude Miller is, among other things, a director of faces who has been influenced by Ingmar Bergman. Here he makes eloquent use of close-ups of faces and eyes. The late Francois Truffaut, who also did much along those lines, and with whom Miller worked on seven films,would have been pleased.

Have you ever been leading a session and been faced with the statement, “That’s great, but what does it cost?” The new economics of education rely on free as the baseline of worth in the classroom, and that’s bad for ideas and growth.
I know that money is tight1. I’ve spent hundreds of my own dollars on classroom supplies, materials, lessons, and tissues…so many tissues. I’m concerned that the value of materials is rooted in what it costs rather than its instructional value, which is both good and bad for education.
We need to differentiate between the free sharing of ideas and the free sharing of products.
The two are not synonymous, yet they are often equivocated. Consider the following:
I may share an idea on Twitter, my blog, or at a conference. It could be a lesson plan, a lab activity, or something to do with students learning. I have no ownership over any part of it, other than it’s something I came up with. The idea is ephemeral…it lives and dies with the action that’s taken.
Someone reads or hears the idea and runs with it. They create a lesson plan, supplemental materials, and other products which can be shared – maybe even a curriculum or an ebook.
Are they wrong for wanting to get some return on their investment of time and energy by asking for a small fee for those materials?
Depending on who you talk to, yes.

I didn’t ask anyone, but I know that making a living off of selling content is really, really hard in today’s education economy. What bothers me the most is that people (individuals, not corporations) who sell materials rather than giving them away are really hearing, “My time as a teacher is valuable, but not what I make with that time.”
A refrain I hear is, “I give all of my materials away for free, so others should do the same.” We’re projecting our own values onto others in the community! I can’t think of a much more damaging sentiment to communicate to colleagues. I’d even go so far as to say it’s bordering unethical behavior by expecting others to work with their products in a way that suits the community rather than their own goals. You can better a community and make money at the same time.
How many entrepreneurs have been stifled because of the “free-and-only-free” expectation? How many conference sessions have been unheard (or even commandeered) because it didn’t focus on free stuff? An economy of free isn’t sustainable, and I’m worried we’re losing valuable insight and growth opportunities because of the path we’re on.
Ideas vs. products. It’s important.
1. I know I’m not in the classroom right now, but I still experience this reaction when I make suggestions of resources for use in the classroom. Free isn’t always worth the hidden costs.

More comments:
"It speaks OVER the first few seconds of the track, so you can't hear the beginning of the track. I want to control when it speaks, for instance, to speak completely before playing the track so no interference, or possibly speak most of it before and then fade in the track, etc. (much like floater timing sliders now, with relative volumes of announcement vs song being like opacity). I also wish I could configure which fields it speaks and in what order. Also, this widget won't change to other voices, and PC voices are *awful*. Should at least allow config of which voice."

The reality is instead data scientists spend on it less than 10% of their time, while 50-80% of it is actually used to prepare data. - Difference between Explanation (statistical modeling) and Prediction (data mining / machine learning) - Modeling steps for Supervised Learning: - 1] Split data into Training and Testing set.

This happens when too many data elements are used in model training. A sign of overtraining is when you get a high level of prediction accuracy, such as anything close to 100%. - Another common practice to improve model performance, and minimize the chancec to overfit, is cross-validation. This method splits the data into subsets of the full dataset to ensure you're not overfitting a model to one training set. --- background-image: url(wheel06.png) # Data Presentation .pull-right-dswf[ - Document - Flat File (CSV, TSV, FWF) - Spreadsheet - Reporting System - Dashboard - Web Application ] ??? --- background-image: url(wheel07.png) # Data Integration .pull-right-dswf[ - Containerization ] ??? - This is the implementation step that's often left to the developers and devOps who "owns" the product(s). - It's more and more common though that data scientists are involved, see the "dataOps". --- background-image: url(wheel08.png) # Data Monitoring .pull-right-dswf[ - ] ??? --- # Thank You! - [

[gecode-users] Question about branching
Christian Schulte
cschulte at kth.se
Tue Feb 10 14:52:37 CET 2009
Hi,
no there is no way to find the x, in particular as some branchings might not
have an array of variables.
There is not even the notion of a current branching (there are two current
branchings: one that is used for status() and the other that is used for
commit() during recomputation).
Branchings are designed to just implement a particular interface that's it.
Maybe you tell us what you want to do?
Then, reflection will be gone (see my next mail as to why) and there is
currently no way to get the actors (unless you iterate over the list of
actors, check how the function propagators() counting the number of
propagators is implemented).

Subject: [gecode-users] Question about branching
Hi,
I try to make a new search engine. In the member function "explore(void)" of
my engine I need to access to the "ViewArray x" of the current branching of
the space.
I have two problems :
- First, how to get the current branching of a space? With reflexion I can
only
get a SpecActor on a branching, but not the branching object itself.
The only way I found was to make some fields of the "Space" class being
public.
Furthermore I have no clue about the base class of the actor, so I must
assume
that all branchings are instances of the "ViewValBranching" class.
- How to get the "ViewArray x" of a ViewValBranching ? As for previous
point,
I have to make the field being public.
I have another question. I looked at the SVN trunk and I saw that reflexion
has
been removed and won't be present in Gecode 3.0. Is there a way to get
(print)
actors of a space? It is very usefull for debugging code and seing what
happened.
Thank you very much for your help.
Cheers,
Vincent

USD/CAD technical analysis: On the front-foot above 100-day SMA
by Anil Panchal- USD/CAD buyers again aim for 200-day SMA.
- The 11-week-old falling trend line adds to the resistance.
- 23.6% of Fibonacci retracement limit immediate declines.
Having bounced off 100-day SMA, USD/CAD again aims at 200-day SMA while taking the bids to 1.3215 during the Asian session on Tuesday.
In addition to the 200-day Simple Moving Average (SMA) level of 1.3276, 50% Fibonacci retracement level of June-July downpour at 1.3290 and a descending trend line since September 03 also challenge bulls around 1.3315.
On the downside, pair’s daily closing below 100-day SMA level of 1.3200 could drag it closer to 23.6% Fibonacci retracement, at 1.3145.
Though, any further declines below 1.3145 might not hesitate to drag the pair towards 1.3100/1.3095 support area.

STEP 14: Browser Compatibility: Using Music Object
|
In the previous step we saw how we could use an EMBED tag nested inside an OBJECT to achieve compatibiltiy with both Netscape Navigator and Microsoft Internet Explorer. While this does work reliably, one problem is that it is quite a bunch of HTML to type each time you wish to play some background music. There are quite a few attributes in the EMBED tag that must be echoed as parameters of the OBJECT tag, opening up the possibility of errors occurring after several generations of updates. Another problem is that using this approach is only really appropriate for background music and it doesn't scale well into the vast world of interactive possibilities offered through the Music Object API.
An easier way to embed background music in a way that can scale well into full-blown interactive sonification is to use the Music Object API's Music.magicEmbed static method. This method allows one to embed non-scriptable Player instances in a way that is compatible with both Navigator and Internet Explorer, without having to worry about the specific differences between the EMBED tag and the OBJECT tag.
The following before-and-after example shows how the cross-browser EMBED-OBJECT tag combination from the previous step in this tutorial is translated to use the Music.magicEmbed method.
| BEFORE (Using EMBED & OBJECT tags) |
<OBJECT SRC="trance.rmf" WIDTH=144 HEIGHT=60 CLASSID="CLSID:B384F118-18EE-11D1-95C8-00A024330339" CODEBASE="http://download.beatnik.com/beatnik-player/beatnik-player.cab" > <PARAM NAME="WIDTH" VALUE="144"> <PARAM NAME="HEIGHT" VALUE="60"> <PARAM NAME="DISPLAY" VALUE="SONG"> <PARAM NAME="AUTOSTART" VALUE="FALSE"> <PARAM NAME="LOOP" VALUE="FALSE"> <EMBED SRC="trance.rmf" WIDTH=144 HEIGHT=60 DISPLAY=SONG AUTOSTART=FALSE LOOP=FALSE TYPE="audio/rmf" PLUGINSPAGE="http://www.beatnik.com/to/?player" > <\OBJECT> |
| AFTER (Using the Music.magicEmbed Method) |
<SCRIPT SRC="music-object.js"></SCRIPT>
<SCRIPT LANGUAGE=JavaScript><!-- //
Music.magicEmbed (
'SRC="trance.rmf" ' +
'WIDTH=144 ' +
'HEIGHT=60 ' +
'DISPLAY=SONG ' +
'AUTOSTART=FALSE ' +
'LOOP=FALSE'
);
// --></SCRIPT>
|
In both the before and after stage in the above comparison, the text that is highlighted indicates the customizable attributes / parameters for the embedded Player instance. From the comparison, you will notice how much simpler the Music.magicEmbed approach is. Most notably, there is no need to duplicate values in both the EMBED and OBJECT tags. The Music.magicEmbed method also automatically takes care of the TYPE and PLUGINSPAGE attributes for the EMBED tag, as well as the CLASSID and CODEBASE attributes for the OBJECT tag, so these don't have to be specified when calling the Music.magicEmbed method.
It's important to note that you cannot use the Music.magicEmbed method unless you have first sourced in the "music-object.js" JavaScript file, since the method is defined inside this file. This is done with the statement <SCRIPT SRC="music-object.js"></SCRIPT>. In our example we're assuming that the "music-object.js" file exists inside the same folder as the HTML document that is using it. If the file was in a different folder, then we'd have to specify the correct relative path to it, just like any other Web site resource (such as a GIF or JPEG image file).

There are four base visible classes on which the other object libraries are founded.
VisClass
is the most basic and at the root of the visible class tree. Under it are
VisCompClass
and
VisTextClass
.
VisContentClass
is a subclass of
VisCompClass
.
VisTextClass
is special in that it is rarely subclassed as it already contains nearly all the functionality an application will need from a visible text object.
The other three classes are typically subclassed by applications. None of the three can draw itself; instead, the subclass must handle
MSG_VIS_DRAW
, the message that indicates the object must draw itself. The three different classes are used as follows:
VisClass
VisClass
is the head of the visible class tree and therefore is the most broad-based in functionality.
VisClass
objects can not have children and therefore can only exist as the leaves of the object tree.
VisCompClass
VisCompClass
provides a composite
VisClass
object. Essentially, this class is the same as
VisClass
except that it can have children. It also includes several special geometry options that allow it to manage and place its children as well as set their bounds.
VisContentClass
VisContentClass
is used only as the content of a GenView. It is a subclass of
VisCompClass
and therefore can have children and manage them with the same geometry features available to VisComp. In addition, the VisContent interacts with the GenView to handle input and drawing. The content can interact with the view to determine sizing behavior as well as input behavior.

ESB to close to two power stations in the midlands; 90 workers to be affected
by By Digital Desk staffESB has announced it is closing two power stations in the midlands. The company is currently meeting with employees from West Offaly and Longford's Lough Ree power stations to inform them of the plan for the closure of the stations.
The government recently announced the creation of a €6 million Just Transition Fund for the midlands, and the ESB has announced that it will make an additional contribution of €5 million to the fund.
The ESB says it's a matter of significant regret, and it very much appreciates the commitment of staff. Up to 90 workers are believed to be affected.
The ESB said it submitted an application to An Bord Pleanála in 2018 seeking planning permission to transition West Offaly Power from peat to biomass over a number of years starting in 2020.
However, the planning application was rejected by An Bord Pleanála in July of this year. The ESB said:
"Since then, ESB has undertaken a review of the options for both West Offaly Power and Lough Ree Power stations post 2020 in the context of the requirements of the single electricity market (SEM).

"Having considered the key planning, environmental and commercial issues associated with peat and biomass, regrettably there is no viable business model beyond 2020.
"Therefore both stations will cease generation of electricity at the end of December 2020."
It said given its long history of power generation in Shannonbridge and Lanesboro, "this is a matter of significant regret for ESB", adding that it very much appreciates the commitment of our staff and the support of the community over many decades.


Inline vs Inline-block
26 Jul 2014
There are different ways to position content in HTML to make your page look good. Two of these are the CSS properties display:inline and display: inline-block. We are going to examine the differences between these two styles.
Inline
.inline{
display: inline;
background: grey;
}

 Lorem ipsum dolor...

 Lorem ipsum dolor...

Inline is the default property for some elements such as
and
. Inline positioning displays content sequentially without any spaces or line breaks. As the name “inline” implies, it basically keeps things on the same horizantal line.
The image above is actually two HTML paragraphs. Normally there would be a break between the two and they would be stacked vertically, but here because we use display: inline, the second paragraph begins immediately following the end of the first and therefore they appear as one.
Inline-Block
.inline{
display: inline;
background: grey;
}

 Lorem ipsum dolor...

 Lorem ipsum dolor...

Inline-block is a method of displaying HTML in block on the same horizantal line. Normally display: block displays HTML elements stacked vertically. Display: inline-block stacks them horizantally. It can be used as an alternative to float.
The above image displays the same two paragraphs using display: inline-block. As the name inline-block suggests, the elements are displayed as blocks on the same horizontal line. If they were displayed as regular blocks they would display as vertically stacked.


Returns TRUE if the current member of the specified dimension is in the specified generation.
Syntax
@ISGEN (dimName, genName | genNum)
| Parameter | Description |
|---|---|
dimName |
The name of a dimension. |
genName or genNum |
Generation name specification, or a non-negative number that defines the number of a generation. |
Example
In the Sample Basic database:
@ISGEN(Measures,3)
Returns TRUE if the current member is Margin, Total Inventory, or Margin %, because these members are all in generation 3 of the Measures dimension.
@ISGEN(Market,2)
Returns FALSE if the current member is New York or Market, because these members are not in generation 2 of the Market dimension.

SVL_QUERY_REPORT
Amazon Redshift creates the SVL_QUERY_REPORT view from a UNION of a number of Amazon Redshift STL system tables to provide information about executed query steps.
This view breaks down the information about executed queries by slice and by step, which can help with troubleshooting node and slice issues in the Amazon Redshift cluster.
SVL_QUERY_REPORT is visible to all users. Superusers can see all rows; regular users can see only their own data. For more information, see Visibility of Data in System Tables and Views.
Table Columns
| Column Name | Data Type | Description |
|---|---|---|
| userid | integer | ID of user who generated entry. |
| query | integer | Query ID. Can be used to join various other system tables and views. |
| slice | integer | Data slice where the step executed. |
| segment | integer |
Segment number. A query consists of multiple segments, and each segment consists of one or more steps. Query segments can run in parallel. Each segment runs in a single process. |
| step | integer | Query step that executed. |
| start_time | timestamp | Exact time in UTC when the segment started
executing, with 6 digits of precision for fractional seconds. For
example: 2012-12-12 11:29:19.131358 |
| end_time | timestamp | Exact time in UTC when the segment finished
executing, with 6 digits of precision for fractional seconds. For
example: 2012-12-12 11:29:19.131467
|
| elapsed_time | bigint | Time (in microseconds) that it took the segment to execute. |
| rows | bigint | Number of rows produced by the step (per slice). This number represents the number of rows for the slice that result from the execution of the step, not the number of rows received or processed by the step. In other words, this is the number of rows that survive the step and are passed on to the next step. |
| bytes | bigint | Number of bytes produced by the step (per slice). |
| label | char(256) | Step label, which consists of a query step name
and, when applicable, table ID and table name (for example,
scan tbl=100448 name =user ). Three-digit table IDs
usually refer to scans of transient tables. When you see
tbl=0 , it usually refers to a scan of a constant
value.
|
| is_diskbased | character(1) | Whether this step of the query was executed as a
disk-based operation: true (t ) or false
(f ). Only certain steps, such as hash,
sort, and aggregate steps, can go to disk. Many types of steps are
always executed in memory.
|
| workmem | bigint | Amount of working memory (in bytes) assigned to the query step. This value is the query_working_mem threshold allocated for use during execution, not the amount of memory that was actually used |
| is_rrscan | character(1) | If true (t ), indicates that
range-restricted scan was used on the step.
|
| is_delayed_scan | character(1) | If true (t ), indicates that
delayed scan was used on the step.
|
| rows_pre_filter | bigint | For scans of permanent tables, the total number of rows emitted before filtering rows marked for deletion (ghost rows) and before applying user-defined query filters. |
Sample Queries
The following query demonstrates the data skew of the returned rows for the query with query ID 279. Use this query to determine if database data is evenly distributed over the slices in the data warehouse cluster:
select query, segment, step, max(rows), min(rows), case when sum(rows) > 0 then ((cast(max(rows) -min(rows) as float)*count(rows))/sum(rows)) else 0 end from svl_query_report where query = 279 group by query, segment, step order by segment, step;
This query should return data similar to the following sample output:
query | segment | step | max | min | case ------+---------+------+----------+----------+---------------------- 279 | 0 | 0 | 19721687 | 19721687 | 0 279 | 0 | 1 | 19721687 | 19721687 | 0 279 | 1 | 0 | 986085 | 986084 | 1.01411202804304e-06 279 | 1 | 1 | 986085 | 986084 | 1.01411202804304e-06 279 | 1 | 4 | 986085 | 986084 | 1.01411202804304e-06 279 | 2 | 0 | 1775517 | 788460 | 1.00098637606408 279 | 2 | 2 | 1775517 | 788460 | 1.00098637606408 279 | 3 | 0 | 1775517 | 788460 | 1.00098637606408 279 | 3 | 2 | 1775517 | 788460 | 1.00098637606408 279 | 3 | 3 | 1775517 | 788460 | 1.00098637606408 279 | 4 | 0 | 1775517 | 788460 | 1.00098637606408 279 | 4 | 1 | 1775517 | 788460 | 1.00098637606408 279 | 4 | 2 | 1 | 1 | 0 279 | 5 | 0 | 1 | 1 | 0 279 | 5 | 1 | 1 | 1 | 0 279 | 6 | 0 | 20 | 20 | 0 279 | 6 | 1 | 1 | 1 | 0 279 | 7 | 0 | 1 | 1 | 0 279 | 7 | 1 | 0 | 0 | 0 (19 rows)


Background:
Bønne Roasting Co. Is a Kitsilano coffee roastery owned and operated by Sevard Blom and his wife Anni. Their roastery, aptly named bønne, which is Norwegian for bean, delivers Nordic flavours and traditions to Vancouver's diversifying coffee house scene.
With cold brew coffee products growing in popularity, bønne Roasting Co. sought the opportunity to launch their own house blend in bottled form for wholesale distribution across Vancouver. It was clear a creating a new brand mark and bottle design would help their company live up to their cultural roots, differentiate on store shelves, and attract an eclectic audience of coffee enthusiasts.
Taking influence from Scandinavian folk art and the rich natural flavours of the brew, I crafted a new logo and cold brew label that stands apart by embracing what coffee lovers enjoy most: the finer details. The contemporary floral arrangement pairs well with bønne’s Nordic roots while maintaining a degree of sophistication that is necessary for attracting the discerning coffee drinker.
I came away from this project with a deeper understanding of Canada’s food & drug regulations, and praise from peers having created a label design that really did stand out from other cold brew beverages.

Abstract: Computational models of visual cortex, and in particular those based on sparse coding, have enjoyed much recent attention. Despite this currency, the question of how sparse or how over-complete a sparse representation should be, has gone without principled answer. Here, we use Bayesian model-selection methods to address these questions for a sparse-coding model based on a Student-t prior. Having validated our methods on toy data, we ﬁnd that natural images are indeed best modelled by extremely sparse distributions; although for the Student-t prior, the associated optimal basis size is only modestly over-complete. 1

Poetry for dependency management
As we’ve seen in the first article, it is crucial to switch to different python version and pyenv helped us with this. If you haven’t read this article, I highly recommend it.
Dependency management is a critical part of software development. It can be difficult to keep track of all the dependencies your project relies on, and it’s easy to introduce new ones unintentionally. A well-defined dependency management strategy can help you avoid these problems.
There are a number of different dependency management tools available, each with its own strengths and weaknesses. The most popular is definetely pip. So why using another depended resolver?
When choosing a dependency management tool, it’s important to consider your team’s needs and preferences. Some teams prefer a tool that is widely used and supported, while others might prefer a tool that is more tailored to their specific needs.
What I do like about poetry is, that the update and installation are encapsulated via a lock file and a toml file. You can add a library to your toml file and poetry tries to resolve the dependencies with the lock file. If everything works just fine you will not get any errors. But if you receive one, you can focus on that specific library with this version and how to add or update it. This is one killer feature for me, why I chose poetry.
Additionally, I appreciate the easy process of building my new package. And now we can see it in action.
Poetry in action
First of all, I like to have my venv within my project.
1
poetry config virtualenvs.in-project true
Now we can start with how I create my project
First of all I create a new project folder with
1
poetry new foo
This is gonna be the directory tree of our new project.

For now you don’t see any lock file and this is because we did not add any dependency.
Let’s just add one dependency which shouldn’t be missed in any of my projects, numpy.

Using version ^1.22.4 for numpy
Updating dependencies
Resolving dependencies... (1.0s)
Writing lock file
Package operations: 9 installs, 0 updates, 0 removals
• Installing pyparsing (3.0.9)
• Installing attrs (21.4.0)
• Installing more-itertools (8.13.0)
• Installing packaging (21.3)
• Installing pluggy (0.13.1)
• Installing py (1.11.0)
• Installing wcwidth (0.2.5)
• Installing numpy (1.22.4)
• Installing pytest (5.4.3)
Et Voila, we have a poetry.lock file. Btw, with this command we just added numpy and all its dependencies (i.e. pytest). We can also check this out in our lock file. In our pyproject.toml, we can only see numpy and it’s version. There are also many more possibilities with version constraints, but for now it should be fine.
Let’s have a look at the pyproject.toml:

[tool.poetry]
name = "foo"
version = "0.1.0"
description = "This is just a poetry demonstration"
authors = ["Malte"]
[tool.poetry.dependencies]
python = "^3.8"
numpy = "^1.22.4"
[tool.poetry.dev-dependencies]
pytest = "^5.2"
[build-system]
requires = ["poetry-core>=1.0.0"]
build-backend = "poetry.core.masonry.api"
We can basically differentiate the toml file in 4 blocks. The tool.poetry is for metadata of the package. tool.poetry.dependencies is for dependencies in a production system tool.poetry.dev-dependencies is for dev-dependencies build-system is used for the build system ( I know, I should not explain it with the same words ;-) )
If you want to add a dev-dependency you can just do it like
1
poetry add -D pytest
and you are good to go.
Furthermore you can add another block to customize the dependency installation to your needs.
As an example you want a complete installation of dask. In this case you would achieve this with pip
1
pip install dask[complete]
In our case, we just want to add dask with poetry and afterwards make it optional.
1
poetry add "dask[complete]"
With the result
1
dask = {extras = ["complete"], version = "^2022.5.2"}
But now, we don’t want this package all the time to be installed, only in some cases. So we just add another block to our pyproject.toml and change the dask entry:
1
2
3
4
dask = { extras = ["complete"], version = "^2022.5.0", optional = true }
[tool.poetry.extras]
ml = ["dask"]
Now poetry listens to the shell parameter –extras ml. If you are now going to install the package with the command
1
poetry install --extras ml --no-dev
you install all packages that are not optional (by default), also all packages bundled in the parameter “ml” and you don’t install dev-dependencies. Fancy, isn’t it?
Now you can just checkout your python venv with
1
poetry shell
and start coding in your src folder (here it is foo).
Whenever you feel like updating a dependency, you can just do
1
2
poetry update # update all packages
poetry update numpy # update single package
After all the coding fun, you just want to build and publish it.
1
2
poetry build #build wheel and tar.gz
poetry build --format wheel
With just one command you create your wheel and tar.gz file

├── poetry.lock
├── pyproject.toml
└── tests
├── __init__.py
└── test_foo.py
3 directories, 8 files
Now you might realize that you just build your version with the incorrect version. Don’t worry, you don’t have to open pyproject.toml by hand, poetry can help you out!
1
2
3
poetry version prerelease # 0.1.1-alpha.0
poetry version patch # 0.1.1
poetry version minor # 0.2.2
Now you are ready to publish it to your private repository.
Now you can just add your repository path and credentials:
1
2
poetry config repositories.foo https://foo.bar/simple/
poetry config http-basic.foo username password
Now you can just publish it
1
poetry publish
After you have published everything, there is just one more thing to do.
Set up your pyproject.toml, so that you use your private repository as well. You remember, when we first installed numpy and dask. By default, poetry looks for package at pypi. But as you may have learned, we can easily change that.
Add this to your pyproject.toml
1

4
[[tool.poetry.source]]
name = "foo"
url = "https://foo.bar/simple/"
default = true
Upgrade older projects to poetry
There are two more things, I’d like to add and had to do it quite often. You might have older projects, which you want to upgrade to poetry. You can do that and it is not that complicated. (spoiler: We need some bash magic for convenience).
First of all: Go to your project root folder and create a pyproject.toml.
1
poetry init -n
I like to create my toml file in noninteractive mode. That’s why I added this parameter.
Now you just need your requirements.txt and your pyproject.toml to be in the project folder and run this command.
1
RUN awk '{print $1}' requirements.txt | xargs -n1 poetry add
It just adds every library line by line and ignoring (!) the version. If pip did a good job, we should have a working virtual environment, managed by poetry.
Export to requirements.txt
You can’t avoid to create a requirements.txt (at least in the near future). Poetry has of course a converter for this.
1
poetry export -o requirements.txt --extras ml --no-dev --without-hashes
I just added all parameters that came to my mind. You want of course the ml extras from above, and you also want to ignore the dev- dependencies. The last parameter “without-hashes” is just to make it more readable and ignore the hashes that are created from the poetry.lock file.
I really hope it helped you.
Conclusion
Pyenv & Poetry are great tools and helped me a lot during my projects.
Many thanks to

Abstract
This document describes the transfer of supporting materials. The schema is part of the HR-XML Consortium effort to define an XML vocabulary to support business transactions in the Human Resource domain.

8.1 Embedded Data – Encoded Content
8.2 Embedded Data – Non-encoded Content
Supporting materials are commonly passed with HR transactions. Examples may include a picture associated with a resume, a copy of a driver’s license sent as part of a background check, proof of good health sent with a life insurance enrollment, a copy of diploma or license, or a copy of a pay stub. Supporting materials may also include visual/audio media and binary data.
Some workgroups have constructed schema to pass supporting materials. This project would create a generalized structure to replace these structures.
The objective of this project is to create schema reusable across workgroups for passing miscellaneous documents by reference or by value. The project will also specify how workgroups can handle element values with images and other hard to code data types.
Many transactions need to include, attach, or point to supporting documentation. This may affect numerous HR domains such as screening, enrollment and recruiting. Since this is cross-domain issue, the project will be undertaken by the CPO workgroup.
At a minimum, this object will support existing schemas for business processes in assessment, recruiting (resume) and background checking. It also will support any other HR business process that needs a general way of specifying supporting materials, such as SIDES, enrollment, and payroll.
Supporting materials come in many different data formats, including text, formatted text, images, MS Word documents, PDFs, etc. They are very much like e-mail attachments. We need to handle at least 80% of common cases.
Supporting materials are sometimes just a reference to an existing document on line somewhere, but sometimes the document itself needs to be included in the structure. This may be embedded or attached to the document. The specification will handle all three types of supporting materials.
This standard is designed to handle electronic documents associated with common human resources transactions. Examples include formatted resumes, pictures of job applicants, and images of official records. These items may be electronically signed.
Items outside of the design scope for this standard are supporting materials that cannot be either referenced with a URL, attached via electronic envelope, or practically embedded with base64 encoding. For example, this standard is not designed to send a physical object, to track a separate physical mailing, or to send a terabyte-sized database as base64 embedded data.
While this standard can pass copyright information, it has no direct support for digital rights enforcement.
Because this is a Cross-Process Object, and not a transaction itself, the roles of trading partners in using this specification will be those of the business processes that pass supporting materials. Some of the common patterns for trading partner use of these entities are outlined in the use cases in the next section.
Supporting materials may be included in a variety of business transactions.

These elements are defined in Section 2: The Dublin Core Metatdata Element Set of the following Dublin Core document: http://dublincore.org/documents/dcmi-terms/
Although Title and Format are outside the ExtendedMetaData section, they are defined here along with the other Dublin Core elements.
|
Element |
Definition |
Business Rule |
Example |
|
Title |
A name given to the resource. Typically, a Title will be a name by which the resource is formally known. |
|
|
|
Format |
The physical or digital manifestation of the resource. Typically, Format may include the media-type or dimensions of the resource. Format may be used to determine the software, hardware or other equipment needed to display or operate the resource. |
Recommended best practice is to select a value from a controlled vocabulary (for example, the list of Internet Media Types [MIME] defining computer media formats). |
Examples of dimensions include size and duration. |
|
Creator |
An entity primarily responsible for making the content of the resource. Typically, the name of a Creator should be used to indicate the entity. |
|
Examples of a Creator include a person, an organization, or a service. |
|
Subject |
The topic of the content of the resource. Typically, a Subject will be expressed as keywords, key phrases or classification codes that describe a topic of the resource. |
Recommended best practice is to select a value from a controlled vocabulary or formal classification scheme. |
|
|
Description |
An account of the content of the resource. Description may include but is not limited to: an abstract, table of contents, reference to a graphical representation of content or a free-text account of the content. |
|
|
|
Publisher |
An entity responsible for making the resource available. Typically, the name of a Publisher should be used to indicate the entity. |
|
Examples of a Publisher include a person, an organization, or a service. |
|
Contributor |
An entity responsible for making contributions to the content of the resource. Typically, the name of a Contributor should be used to indicate the entity. |
|
Examples of a Contributor include a person, an organization, or a service. |
|
Date |
A date associated with an event in the life cycle of the resource. Typically, Date will be associated with the creation or availability of the resource. |
Recommended best practice for encoding the date value is defined in a profile of ISO 8601 [W3CDTF] and follows the YYYY-MM-DD format. |
|
|
Type |
The nature or genre of the content of the resource. Type includes terms describing general categories, functions, genres, or aggregation levels for content. |
Recommended best practice is to select a value from a controlled vocabulary (for example, the DCMI Type Vocabulary [DCMITYPE]). To describe the physical or digital manifestation of the resource, use the Format element. |
|
|
Identifier |
An unambiguous reference to the resource within a given context. |
Recommended best practice is to identify the resource by means of a string or number conforming to a formal identification system. |
Example formal identification systems include the Uniform Resource Identifier (URI) (including the Uniform Resource Locator (URL)), the Digital Object Identifier (DOI) and the International Standard Book Number (ISBN). |
|
Source |
A reference to a resource from which the present resource is derived. The present resource may be derived from the Source resource in whole or in part. |
Recommended best practice is to reference the resource by means of a string or number conforming to a formal identification system. |
|
|
Language |
A language of the intellectual content of the resource. |
Recommended best practice is to use RFC 3066 [RFC3066], which, in conjunction with ISO 639 [ISO639], defines two- and three-letter primary language tags with optional subtags. |
Examples include "en" or "eng" for English, "akk" for Akkadian, and "en-GB" for English used in the United Kingdom. |
|
Relation |
A reference to a related resource. |
Recommended best practice is to reference the resource by means of a string or number conforming to a formal identification system. |
|
|
Coverage |
The extent or scope of the content of the resource. Coverage will typically include spatial location (a place name or geographic coordinates), temporal period (a period label, date, or date range) or jurisdiction (such as a named administrative entity). |
Recommended best practice is to select a value from a controlled vocabulary (for example, the Thesaurus of Geographic Names [TGN]) and that, where appropriate, named places or time periods be used in preference to numeric identifiers such as sets of coordinates or date ranges. |
|
|
Rights |
Information about rights held in and over the resource. Typically, a Rights element will contain a rights management statement for the resource, or reference a service providing such information. Rights information often encompasses Intellectual Property Rights (IPR), Copyright, and various Property Rights. |
If the Rights element is absent, no assumptions can be made about the status of these and other rights with respect to the resource. |
|
Human resources data, by its very nature, is personal data. The laws of many jurisdictions as well as codes of fair information practice require organizations to handle personal data in a way that protects individuals from loss of privacy.
The data exchange specifications developed by the HR-XML Consortium are designed to be useful across many jurisdictions and within a variety of business contexts. It is not feasible for the HR-XML Consortium to develop specific privacy guidance for every jurisdiction or business context in which the Consortium's specifications might be implemented. When implementing data exchanges using the HR-XML Consortium's data definitions (or, for that matter, using any other type of data exchange mechanism), organizations are advised to examine the privacy protections that may be required under applicable law and codes of fair information practice.
For information on protecting personal data, general references include: European Union Data Protection Directive (95/46/EC); the Association Computing Machinery Code of Ethics (1992); Canadian Standards Association Model Code for the Protection of Personal Information (1995 – PIPEDA); and U.S.-EU Safe Harbor Principles and FAQs (2000).

Sorry about taking it down, but it is for a good cause. I will be taking it down at the end of the work day today so get those last battles in.

Music can be a fascinating topic. So many different genres with several adoring fans, lots of whom think a particular one is best.
All too often there are discussions and arguments on why or if a certain genre should be classified as terrible.
An apt encapsulation of "one man's meat is another man's poison".
This got us thinking, what if we could get both men to see what the other sees?
Method
Based on a user's recent listens, our model generates 10 songs we believe the user won't be interested in. The model looks at the audio features of a user's top recent tracks like "speechiness", "loudness", "danceability" then suggests songs that are highly dissimilar. For students of several genres, note that our model uses your top 10 recent tracks so you could get a genre on the other side of the spectrum that you haven't listened to in a while. Be aware the more further out of the norm your bad suggestions are, the longer it could take to generate. Please be a bit patient. However you can click "Generate Suggestions" again if it's taking extra long.We also retrieve the lyrics for the songs via the Genius API to come up with the name of the playlist for these 10 songs. See if you can guess which song resulted in this newfound playlist's name. Might require listening to some of these songs though ;) Our app has a mini player embedded so you can listen to the songs right within the app. We absolutely do not expect you to like any of the songs in our playlist.
If you've had enough of the bad songs, get some reprieve by getting a playlist of good suggestions. Simply select the "Generate good suggestions" right below the player and get 10 songs you should like. All the properties of the bad playlists apply to the good playlist suggestions, right down to naming the playlists. Want to add a particular song to your liked songs? Click the Spotify logo and head on over to its Spotify page.
Head on over to our main page and start generating some playlists. Have fun!
For the nerds: Check our our GitHub for the source code.

General-Market Broadcast: “Aliens”
This campaign poked fun at a health-challenged alien nation so that we could dramatically and creatively pay off the superpowers that milk has. The aliens were mesmerized by cows and their ability to provide milk, which helped rid their weak and ailing population of broken bones, brittle hair, sallow skin and PMS.


Bangladesh pacer Shahadat Hossain banned for five years for assaulting teammate Arafat Sunny
by Kumar ShashwatWhat’s the story?
Bangladesh fast bowler, Shahadat Hossain has been found guilty of physically assaulting his Dhaka Division teammate, Arafat Sunny in an encounter against the Khulna Division in the National Cricket League.
Follow Sportskeeda for more Cricket news .
In case you didn’t know
Shahadat had been a regular in the Bangladesh set-up during the late 2000s and the early 2010s when he made a total of 95 appearances for his country across all formats. The fast-bowler played 38 Tests, 51 ODIs and 6 T20Is during that period.
Shahadat's name was embroiled in controversy back in 2015 when he was found guilty of a similar offence when he attacked his household help. The above also led to a ban and a bit of time away from the game.
The heart of the matter
The incident occurred during a match between the Dhaka Division and the Khulna Division when Shahadat and Arafat got into a confrontation regarding the way the ball was being shined.
The fight got so severe that teammates of the aforementioned players had to step in to stop Shahadat from inflicting more damage.
Consequently, the fast-bowler copped a BDT 1 Lakh fine from the Bangladesh Cricket Board, an amount which roughly equates to USD 1200.
What’s next?
Shahadat has not played for Bangladesh since 2015 and the tenure of his ban seems likely to end his international career. Though the pacer might still harbour hopes of a comeback into the domestic circuit, it seems a long road to redemption at this juncture.


Strip out and rebuild the handset to use as handheld microphone.
I saw instructions on the net. It was not difficult but also not a
straight
road to the final product. This is how I did it...
Strip out and rebuild the handset to use as handheld microphone.
I saw instructions on the net. It was not difficult but also not a
straight
road to the final product. This is how I did it...
This is the phones microphone.
Messy: one red+ and one black- cord for the signalling. One yellow for
shielding
and two, also yellow!, cords going up to the speaker.
Disassembling of the handset and spray it with chrome, silver, colour.
Must be Chrome!
I thought that the phone coat was made of Bakelite; the first industrial
made plastic.
I found out that Bakelite is not indigestible. But this handset was very easy to melt
and then reshape to desired design. It actually burns very well.
XLR connector. Cannon X Series Latch Rubber.
I used the male connector (hane) where 1 is the shield (not used), 2 hot,
3 cold.
So two cords connected to pin two and three;
did not matter witch cord to which pin; either way works.
This is the phones Carbone microphone.
It does not work that well:
gives a low signal and allot of noise.
Can improve this by connecting a 9V battery to it but I didn't bother
doing that this time. Instead I used the phones speaker as a microphone - better.
Experimenting with the connections.
Used the red and black cord for the
signalling and skipped the yellow for shielding.
Warning! When soldering the cords to the XLR connector;
be careful not to apply too much heat - the connector will melt and be destroyed!

The final product. How does it work?
Well it's alright but can't be compared to my condenser microphone
that I bought from store. But this one will be used as my harmonica
"rock & roll" mic on my tours - Yeah right ;-)
Will I do this again? - You bet I will...

Details
It has been established practice for 60 years to prepare thyrotoxic
patients undergoing thyroidectomy with Lugol's iodine. However, evidence
in support of its claimed benefits, namely a reduction in the vascularity
and friability of the toxic thyroid gland, is scanty. We have therefore determined
the effect of Lugol's iodine on thyroid blood flow, as measured by thyroid uptake
of thallium-201, in nine patients with Graves' disease and one euthyroid patient.
Thallium-201 uptake, as well as serum thyroxine and triiodothyronine, fell
significantly after treatment with iodine. Although not correlated with thyroid
function tests, thallium-201 uptake was significantly correlated with thyroid weight.
These results support the contention that thyroid blood flow is reduced in thyrotoxic
patients treated with Lugol's iodine.
