I want to run a R script file (.r) using batch file.
- I don't know what .r script file is; however, you must remember that a Batch file is just an automated way to execute DOS commands, so the answer to your question is: How do you run a R script file with a DOS command? If you can't do that via a command line, then a Batch file can't do either...Aacini– Aacini2011-07-22 16:17:15 +00:00Commented Jul 22, 2011 at 16:17
- if you're still out there could you please help resolve the controversy here (see comment threads below)?Ben Bolker– Ben Bolker2011-10-25 03:26:18 +00:00Commented Oct 25, 2011 at 3:26

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 1 Comment
I doubt you will be able to run it using a batch file.
http://www.fileinfo.com/extension/r 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.
