Whenever I try to 'run block' to run a block of Julia code in Atom, it just runs the currently selected line. I don't understand what's wrong. I've tried all the different delimiters ('##', '# %%', and '# --') and it still isn't recognizing code blocks. The formatting itself also suggests it's not recognizing the block delimiters.
What am I doing wrong?
The block delimiter is ## with a space after the second octothorpe. Try, for example, ## ---
I just reinstalled Juno/Atom/Julia fresh and everything worked out.

would you please help me? if I have a code including some loops and IFs, how can I debug inside FOR or IF, line by line.
for example
I can use shift+enter for every line. but when it is used for a For all loop will run. Is there any facility to debug inside a loop line by line?
thanks
You can run line by line in e.g. Juno by just highlighting the line, that will not run the entire loop. I'd recommend doing that.
With regards to an actual debugger, there is not currently one available for julia-1.x. But there's Rebugger.jl, it's use is quite advanced though.
ctrl+R no longer works for executing script lines.
This is not a hardware/keyboard problem.
I have also restarted my PC.
I have tried on a different PC.
I have recently switched from using R to using RStudio. I thought this may have something to do with it, so I opened and resaved the script in RStudio, to no effect.
Furthermore, I have created an R-Project folder and have copied the files, including the script in question, into it. Then I started R-Studio and opened the project.
I would like to post my sessionInfo(), but do not know how to do that without executing the command.
Keep in mind that I only use R for stats purposes. I don't know much about informatics or other types of programming etc., so please try to keep it simple for me. Thanks!
In addition to the solution offered above, in Rstudio, Ctrl + Enter does not work if the chunk is broken in .Rmd files.
For example, if you press CTRL + Enter on the following line (2+2), it won't work:
```{r}
2+2
``
The chunk should end three Backtick characters, not two.
The problem was that the script file (for some reason unkown to me) did not have the correct extension (.R). When I added that to the script file extension, it worked fine again.
I ran into a very weird problem: my R code for generating a plot only works if I type it into the console but not when I ran it inside the script (with Ctrl+Enter command)... It's the same problem with all plots (regular plots or ggplots). Also I tried it on two different computers and the same thing happened. Anyone have any idea why this is happening?
One possible reason: I installed the newest version of Rstudio on both computers so it might be an issue with the version. The exact same code worked before on an older version of rstudio...Could this be it? If so, how can I fix it?
I think I figured out what the problem was: the setting in the new version of Rstudio has a default option of outputting the plots inside the Rmarkdown script (at the very end of the script). And that's why I wasn't seeing them. You could change the setting such that it outputs in the console.
Try dev.off() to reset the graphics device.
This helps with a lot of weird graphics behaviour.
Probably too late for the original poster... However, I just ran into the same problem after installing an R update. The way I fixed it was to go to preferences, R markdown, and turn off "show inline output". For me, it was just coming out at the bottom of the chunk instead of in the plot window like I wanted. Hope that helps someone!
I just ran into this problem. I mistakenly put my plot() command inside the r markdown setup chunk. I moved it to its own code chunk and it ran as expected.
I'm writing all my scripts on .R file using R for mac. It is convenient to me because there are colors to highlight the type of commands.
I have a many comments following the # symbol that are useful when I forget about the meaning of my script but they tend to blur my script so that it gets harder to find a given command line.
Is there a way to hide and show these comments ? (Using the programm I'm currently using or another one). What would you suggest as the best program to write R script ?
Thanks a lot !
RStudio supports code folding. You can standardize your comment blocks so that they are recognized as code blocks.
For example, enter this into your RStudio editor
#=======================================================
# this is a comment block
# more comments here
# comments upon comments
and then press Alt+L to fold, and Alt+Shift+L to unfold.
Try RStudio for mac. One of the greatest code writing environment for R there is.
You can also try Emacs, which is more like old-fashioned command line editor. You can find a good guide here.
Has anyone managed to get color syntax-highlighting working in the output of Sweave documents? I've been able to customize the output style by adding boxes, etc. in the Sweave.sty file as follows:
\DefineVerbatimEnvironment{Sinput}{Verbatim}{fontseries=bc,frame=single}
\DefineVerbatimEnvironment{Soutput}{Verbatim}{frame=leftline}
\DefineVerbatimEnvironment{Scode}{Verbatim}{fontseries=bc}
And I can get the minted package to do syntax highlighting of verbatim-code blocks in my document like so:
\begin{minted}{perl}
use Foo::Bar;
...
\end{minted}
but I'm not sure how to combine the two for R input sections. I tried the following:
\DefineVerbatimEnvironment{Sinput}{minted}{r}
\DefineVerbatimEnvironment{Scode}{minted}{r}
Any suggestions?
Yes, look at some of the vignettes for Rcpp as for example (to pick just one) the Rcpp-FAQ pdf.
We use the highlight by Romain which itself can farm out to the hightlight binary by Andre Simon. It makes everything a little more involved---Makefiles for the vignettes etc pp---but we get colourful output from R and C/C++ code. Which makes it worth it.
I have a solution that has worked for me, I have not tried it on any other systems though so things may not work out of the box for you. I've posted some code at https://gist.github.com/797478 that is a set of modified Rweave driver functions that make use of minted blocks instead of verbatim blocks.
To use this driver just specify it when calling the Sweave function with the driver=RweaveLatexMinted() option.
Here's how I've ended up solving it, starting from #daroczig's suggestion.
\usepackage{minted}
\renewenvironment{Sinput}{\minted[frame=single]{r}}{\endminted}
\DefineVerbatimEnvironment{Soutput}{Verbatim}{frame=leftline}
\DefineVerbatimEnvironment{Scode}{Verbatim}{}
While I was at it, I needed to get caching working because I'm using large data sets and one chunk was taking around 3 minutes to complete. So I wrote this zsh shell function to process an .Rnw file with caching:
function sweaveCache() {
Rscript -e "library(cacheSweave); setCacheDir(getwd()); Sweave('$1.Rnw', driver = cacheSweaveDriver)" &&
pdflatex --shell-escape $1.tex &&
open $1.pdf
}
Now I just do sweaveCache myFile and I get the result opened in Preview (on OS X).
This topic on tex.StackExchange might be interesting for you, as it suggest loading the SweaveListingUtils package in R for easy solution.
