I want to execute a R script in R Studio using batch file. I know how to execute R script using batch file in R though. When I try to execute using the following:
"C:\Program Files\RStudio\bin\rstudio.exe" CMD BATCH --vanilla --slave "C:\Users\kpappala\Desktop\R schedule\task.R"
It just opens R studio but doesn't execute. Is there a way?
Thanks!
Rstudio is an IDE for R. It isn't R though. It doesn't really even make sense to run it in batch through rstudio.
If you're just saying you want to run a file from within Rstudio that's different and you can just source it or run it in batch via system using a call to R CMD BATCH.
This question was answered here:
batch execute R script.
In short and as Dason said, you Rstudio is just a shell, and doesn't actually run the code. For that use R. Try this instead:
PATH C:\Program Files\R\R-3.1.0\bin;%path%
Rscript "C:\Users\kpappala\Desktop\R schedule\task.R"

I am trying to share some R code with colleagues who don't know R. I have created a batch file so they can just double-click it and run the R script without even opening R. But it creates a .RData file.
My question is, can I prevent R from creating the .RData file?
I've read here Disable saving history that I could disable it through RStudio global options but my colleagues are installing just R and won't need to ever open it, so I am looking for some kind of solution of the likes of options(...) that I can just put in my Rscript, or maybe something that could be speficied in the batch file call.
For anyone curious, I figured it out thanks to #r2evans and this post: https://es.stackoverflow.com/questions/166211/evitar-que-r-cree-ficheros-r-data-y-r-history.
I just had to add --no-save to my batch call like this:
R CMD BATCH --no-save "%file%" NUL
where %file% is the Rscript path. The NUL part is so a .Rout file won't be created after running the batch file.
Also, doing
Rscript.exe "%file%"
runs the Rscript and doesn't produce .RData or .Rout files. The difference is that R messages get printed on the command window as they would in an interactive R session.
I'm having trouble running my R script from Excel VBA.
I wanted to create a Button in Excel with a macro that runs an R script but I've tried so many versions and none worked.
My path to R is "C:\Program Files\R\R-4.1.1\bin\Rscript.exe"
The path to my R Script is "\repo\xyz\18320\38293\one\redirected folder\Desktop\test_run\test\Code\sample.R"
How can I create a shell on VBA which actually executes the Script?
Can I maybe execute the script from the command line and then connect the excel macro to the command line? I didn´t manage to find a solution.
I'm trying for my first time to run an R script from command line on WINDOWS to automate calculation with another program. So I made my R script using R studio and saved it a .bat file with this line
C:\Program Files\R\R-4.0.2\bin CMD BATCH C:\my_directory\my_script.R
Then I putted the script and files the script have to be executed on in the same directory, the one that contains files to run also the program I need. I came throught command line in that directory and I executed the batch file but it doesn't work. I have this as a error message:
"C:\Program Files\R\R-4.0.2\bin"it is not recognized as an internal or external command,
an executable program or batch file.
Where I am wrong? thank you!
You should use Rscript instead, assuming its in your PATH.
E.g.
Rscript C:\my_directory\my_script.R
Or a single expression
Rscript -e "print(123)"
My goal is to use PowerShell to schedule the sourcing of an R script.
My current work flow is that I open RStudio, click the "Source" button in the upper right corner. Then I wait until it's finished, and close RStudio. I change nothing in the R script.
In PowerShell I've been using its Register-ScheduledJob cmdlet to kick off C# programs on a daily schedule. And here's the problem, I can't find an example of effectively using PowerShell to source an R script.
I believe the PowerShell script should probably use the Invoke-Expression cmdlet. But I'm not 100% sure.
To no avail I've tried this:
Start-Process "C:\Program Files\R\R-3.2.4revised\bin\x64\Rterm.exe" -RedirectStandardInput "C:\MyScript.R"
Also, I'd like to avoid the solution that uses CMD BATCH as that's defeating the purpose of using PowerShell.
If just sourcing the R script is what you're looking for then one way to do is something like this
& "C:\Program Files\R\R-3.1.1\bin\Rscript.exe" "C:/Program Files/R/R-3.1.1/tests/demos.R"
where "C:\Program Files\R\R-3.1.1\bin\Rscript.exe" is path Rscript in your local R installation and "C:/Program Files/R/R-3.1.1/tests/demos.R" is path to script you'd normally source() directly in RStudio.
One thing to keep in mind is depending on location of files your R script needs you might need to adjust your script with appropriate setwd()
I want to run a R script file (.r) using batch file.
If R.exe is in your PATH, then your windows batch file (.bat) would simply consist of one line:
R CMD BATCH your_r_script.R
otherwise, you need to give the path of R.exe, so for example:
"C:\Program Files\R\R-2.13.0\bin\R.exe" CMD BATCH your_r_script.R
you can add certain input arguments to the BATCH command, such as --no-save, --no-restore
so it would be
R CMD BATCH [options] your_r_script.R
more info on options, etc at http://stat.ethz.ch/R-manual/R-devel/library/utils/html/BATCH.html
Note: R uses the command "BATCH" to non-interactively evaluate a script located in a file. Here we are running the command "BATCH" from a windows .BAT file, but that's merely a coincidence.
An answer to another question suggests using Rscript.exe, so your batch file would contain:
"C:\Program Files\R\R-3.0.2\bin\i386\Rscript.exe" your_script.R
pause
It is a good idea to add R to the windows environment path. In a comment in this question #chase gave a link that explains how to set the path on windows 7. Once R is added to the windows path, your batch file should become simply :
Rscript.exe your_script.R
pause
You can also directly call a R command by using the -e flag. For example this batchfile will tell R to set its current working directory to Documents, then it will print the working directory:
Rscript.exe -e setwd('Documents');getwd()
pause
I struggled with the syntax with the answers below, but this worked for me in the .bat file:
C:\Windows\System32\cmd.exe /k ""path to Rscript.exe"
"path to .R script""
Be sure to place both the path to Rscript.exe and the script in "" together and separately as above.
I doubt you will be able to run it using a batch file.

Most known programs that use .r files do so for source code files it looks like. You will probably have to compile it using the program it was written for. I guess you could use a command line compiler from a batch file, but I don't know what language or applications you are using.
If you post the script file or give more information about it, we could probably help you better.
