Simple question, but I can't find an answer for R. I found it for Python, but I didn't test it.
When I put to input line of the notebook: setOption(encoding = "Windows-1250") nothing exactly happens. I know (from Python review) I should save it to environment somehow, but how? I created Jupyter Notebook (my first time) from Anaconda by launching button, previously installed all dependencies. Everything's ok (Windows 7).
It's a problem with plotting my locale characters in plots. And maybe, I should encode my characters directly to unicode notation? Like: u003d? But it's time consuming. Any suggestions?

I am trying to use R in VSCode. I downloaded the R extension and followed the steps specified but I keep getting an annoying issue: when I use Alt+126 to write the character '~' in the script everything is fine, but when I run the line, in the R interactive terminal it appears twice. Also, if I use Alt+126 in the R interactive terminal, '~~' appears instead of '~' (two times the character instead of once). I have no idea why this is happening, I tried to uninstall and reinstall both VSCode and R and reset the pc but nothing changed.
I hope somebody knows how to solve this, thanks in advance!
I am using Julia.
I am trying to get some greek characters in Jupyter notebooks.
First I downloaded the latest version of Julia 1.6.2
For the jupyter connection I used anaconda, in julia repl i put ] add IJulia, and then I could chose the Julia kernel in Jupyter.
Then a friend suggested to download vs code (since we got a problem in the working directory with jupyter-anaconda)
In VS code we got no problem with working directories. And to work with notebooks we installed the Jupyter extension. It was working very well, but we got to this problem that we cannot get greek characters.
In Jupyter (anaconda) I could easily put greek characters, like this:
no package needed, nothing, just like that.
However in VSCode I cannot get that, nor "predictive text" or coding suggestions:
Any tips on how to solve this?
Like we are preferring VS Code and we know there's a way to get the greek characters on it, but we don't know how.
Any help is very welcomed.
Thanks in advance.
Check out the docs for the Julia extension in VS code here: https://code.visualstudio.com/docs/languages/julia. Per the comments above, make sure this is installed and you have the Julia kernel selected. You should then see the following:
I'm a Python beginner and recently came across the Atom editor and the package Hydrogen, that implements the Jupyter notebook. I did so after realizing that running the notebook in Chrome consumed way too many resources and also seemed to be a bit slower.
However, the Atom editor and Hydrogen always output prints within a little frame in the code (see image). Unfortunately, it doesn't use the full window width. I also don't see any console/terminal for installing pip libraries.
Is there a way to have the output in a console below the code, just as in Jupyter, and to have a terminal?
this comes most certainly too late, but in case someone else searches for this:
hit control+shift+P / cmd+shift+P and type "toggle output area".
What command line option to use behind Rgui.exe for immediately sourcing an R source file? Instead of having to type source("c:\MyGreatSource.R") manually afterwards. Something like:
Rgui.exe --source "c:\MyGreatSource.R"
Sounds like a simple question answered in any beginner's manual, but I couldn't find such an option anywhere.
I found a workable solution, maybe others are interested. Again, what I like to do is to start the Rgui and work there. All my work environment and functions are defined in an R source file, which I constantly develop further during working. So each of my commands in the GUI starts with Load1(); where Load1 is a function which simply sources my R file, to update the changes I have just made. Obviously, Load1 is also defined in my R file, so I need to get it in the first place, without much effort. I have set the command-line options for neither loading nor saving the workplace; I don't like my old mess from the previous session with test variables and so.
However, my solution now is to just create a workplace RData file which only contains the definition of my Load1 function. This workplace file is easily loaded at every start by just adding its path into the command-line options "D:\MyLoad1.RData"
I use a AutoHotkey Script
run,C:\Program Files\R\R-3.3.3\bin\x64\Rgui.exe
WinWait,RGui (64-bit)
WinWaitActive,RGui (64-bit)
Sleep 100
Send,source("%1%")
Send,{enter}
Is there an easy way to turn of all GUI elements in R and run it solely from the command line on OSX?
I'm trying to replicate the behavior of a remote linux terminal on my OSX machine. Thus plot() should just save a file and things like CRAN mirror selection should be text, not a Tk interface. I'm having trouble finding where to set this behavior.
I had this exact question and wanted a way to do it without changing my existing code. I usually run with graphics support but sometimes I'll run a script on the server for a larger dataset and then I just want the plots to be output somewhere automatically.
In Dirk's answer Ian Fellows gives the simple solution. On the command line in R type:
options(device=pdf)
And then any plots will be written to the current directly to an Rplots.pdf file.
If you want the files to not be plotted at all then use
options(device=NULL)
For the plots you can just direct the output to a file using the pdf() command (or png(), jpeg()...).
I don't own an OS X box, but did you try to unset the X11 environment variable DISPLAY:
DISPLAY="" R --vanilla
When I do that on Linux and query R for capabilties(), x11 comes up as FALSE as desired.
I don't run OSX but you could attempt to run R from the Terminal application, rather than the Mac OSX launcher, and see whether that runs as you need.
As Matti writes, you can send output to files using the following commands; but I don't know if that's really the substance of your question.
png("pngfile.png")
plot(foo)
title(main="bar")
dev.off()
So instead of the quartz graphical object, your output goes to the file.
Similarly, you can output what would normally appear in the terminal to a file.
sink("foo.file")
