So I have 7 variables I am plotting on a Tableau radar chart, I am following along this tutorial: https://www.pluralsight.com/guides/tableau-playbook-radar-chart. Where I have done the exact same calculations, instead of 6 axes, I have 7. Therefore 8 points in my path and dividing the Path equation by 7 instead of 6. I have also created the appropriate dummy variable in the Excel file, by duplicating the first variable and renaming it as a dummy variable to connect the line to. But still the last line does not want to connect.
Path field:
case [Variable]
when "ipsl_risicoperceptie" then 1
when "ipsl_onveiligheids-gevoelens" then 2
when "ipsl_vermijding" then 3
when "Ipersonenoverlast" then 4
when "Iverloedering" then 5
when "HICindex" then 6
when "HVCindex" then 7
else 8
end
Radian field:
IF [Path] = 8 THEN PI()/2
ELSE PI()/2 - ([Path]-1)*2*PI()/7
END
Rest of the fields are exactly the same as the tutorial. What am I missing?

I set.seed in Rmd file to generate random numbers, but when I knit the document I get different random numbers. Here is a screen shot for the Rmd and pdf documents side by side.
In R 3.6.0 the internal algorithm used by sample() has changed. The default for a new session is
> set.seed(2345)
> sample(1:10, 5)
[1] 3 7 10 2 4
which is what you get in the PDF file. One can manually change to the old "Rounding" method, though:
> set.seed(2345, sample.kind="Rounding")
Warning message:
In set.seed(2345, sample.kind = "Rounding") :
non-uniform 'Rounding' sampler used
> sample(1:10, 5)
[1] 2 10 6 1 3
You have at some point made this change in your R session, as can be seen from the output of sessionInfo(). You can either change this back with RNGkind(sample.kind="Rejection") or by starting a new R session.
BTW, in general please include code samples as text, not as images.
I have developed a model in Netlogo and i want to automate the model run.
Basically what i want to do is read the input from either an excel, csv or .txt file and then ask Netlogo to change the inputs in the model accordingly. Run the model for lets say 100 ticks and store the required output from the 100th tick onto either the same file from which the input was read-in or export it onto a different file. Something like this
Trial Input1 Input2 Output
1 10 20
2 20 20
3 10 30
.
.
.
100 20 100
The variables Input 1 and Input 2 are in the interface either as a slider or input button.
Use the Behavior space feature in Netlogo. It's available under the Tool and below is the documentation on the topic.

I am trying to obtain a list of all the DB Tables that will give me visibility on what tables I may need to JOIN for running SQL scripts.
For example, in TCL when I run "LIST.DICT" it returns "Name of File:" for input. I then enter "PRODUCT" and it returns a list of all available fields.
However, Where can I get a list of all my available Tables or list of my options that I can enter after "Name of File:"?
Here is what I am trying to achieve. In the screen shot below, I would like to run a SQL script that gives me the latest Log File Activity, Date - Time - Description. I would like the script to return '8/13/14 08:40am BR: 3;BuyPkg'
Thank you in advance for your help.
From TCL within the database account containing your database files, type: LISTF
Sample output:

DATA &XML& &XML& 19 1
Firstly, UniVerse has no Log File Activity Date and Time.
However, you can still obtain the table's modified/ accessed date from the file system however.
To do this,
You need to have a subroutine accepting a path of the table to return a date or a time.
e.g. SUBROUTINE GET.FILE.MOD.DATE(DAT.MOD, S.FILE.PATH)
Inside the subroutine, you can use EXECUTE to run shell command like istat for getting these info on a unix e.g.
Please beware that for a dynamic file e.g. there are Data and Overflow parts under a directory. You should compare the dates obtained and return only the latest one.
Globally catalog the subroutine
Create an I-Desc in VOC, e.g. I.FILE.MOD.DATE in the field definition of this I-Desc: SUBR("*GET.FILE.MOD.DATE",F2) and Conv Code as "D/MDY2"
Create another I-Desc e.g. I.FILE.MOD.TIME
Finally, you can
LIST VOC I.FILE.MOD.DATE I.FILE.MOD.TIME DESC WITH TYPE LIKE "F..."
alternatively in SQL,
SELECT I.FILE.MOD.DATE, I.FILE.MOD.TIME, VOC.DESC FROM VOC WHERE TYPE LIKE "F%";
I'm doing some optimization using a model whose number of constraints and variables exceeds the cap for the student version of, say, AMPL, so I've found a webpage [http://www.neos-server.org/neos/solvers/milp:Gurobi/AMPL.html] which can solve my type of model.
I've found however that when using a solver where you can provide a commandfile (which I assume is the same as a .run file) the documentation of NEOS server tells that you should see the documentation of the input file. I'm using AMPL input which according to [http://www.neos-guide.org/content/FAQ#ampl_variables] should be able to print the decision variables using a command file with the appearance:
solve;
display _varname, _var;
The problem is that NEOS claim that you cannot add the:
data datafile;
model modelfile;
commands into the .run file, resulting in that the compiler cannot find the variables.
Does anyone know of a way to work around this?
Thanks in advance!
EDIT: If anyone else has this problem (which I believe many people have based on my Internet search). Try to remove any eventual reset; command from the .run file!
You don't need to specify model or data commands in the script file submitted to NEOS. It loads the model and data files automatically, solves the problem, and then executes the script (command file) you provide. For example submitting diet1.mod model diet1.dat data and this trivial command file
display _varname, _var;
produces the output which includes
: _varname _var :=
1 "Buy['Quarter Pounder w/ Cheese']" 0
2 "Buy['McLean Deluxe w/ Cheese']" 0
3 "Buy['Big Mac']" 0
4 "Buy['Filet-O-Fish']" 0
5 "Buy['McGrilled Chicken']" 0
6 "Buy['Fries, small']" 0
7 "Buy['Sausage McMuffin']" 0
8 "Buy['1% Lowfat Milk']" 0
9 "Buy['Orange Juice']" 0
;
As you can see this is the output from the display command.
I'm new to Octave/Matlab and I want to plot a 3D-Graph.
I was able to do so using a predefined formula, like this:
x=1:.1:5;
y=1:.1:5;
[xx,yy] = meshgrid(x,y);
z = sin(xx)+sin(yy);
mesh(x,y,z);
But now the question is how to do the same getting the data from a CSV (for example). I know I can use the function csvread, but the big question is how to format the CSV to contain such data.
An example of doing the same graph above but this time grabbing the data from Excel/CSV would be appreciated. Thanks!
Done! I was finally able to do it!
Here's how I did it:
1) I've created a file in Excel with the X values in the cells A2:A42, and the Y values in the cells B1:AP1 (so you form a rectangle).
2) Then in the cells in the middle I put the formula I want (ie =sin(A$2)+sin($B1))
3) Saved the file as CSV (but separated by spaces!) and manually edited it to look this way (the way QtOctave opens matrix files, in Matlab it might be different). For example (note the extra space before each column):
# Created by Octave 3.2.4, Thu Jan 12 19:32:05 2012 ART <diego#notebook2>
# name: z
# type: matrix
# rows: 3
# columns: 3
1 2 3
4 5 6
7 8 9
(if you're not sure how to do it, do what I did: create a simple matrix and export it to see how the exported file looks like!)
4) Octave has a function under Data -> Load matrix from file, which loads that kind of files. Or actually running this command (varname is the name of the resulting variable):
load("-text", "file-where-the-data-is", "varname")
5) Create the graph (ex is the name of the matrix I've just imported):
x=1:.1:5;
y=1:.1:5;
mesh(x,y,ex)
