Below are some useful scripts for command line processing.

RJobBatch.bat - A Windows command prompt scripts

Given that this script is in the PATH (or in the current directory), a job can be process by calling

RJobBatch --root=jobs-mandelbrot

from the command prompt.

The script can be found by

system.file("bin", "RJobBatch.bat", package="R.batch") and here is what it looks like:

rem ##################################################################

rem # Create R script to start JobBatch$main() in the R.batch package.
echo R.batch::JobBatch$main() > "%TEMP%\JobBatchMain.R"

rem # Start the R script and pass command line options
Rterm --vanilla --args %1 %2 %3 %4 %5 %6 %7 %8 %9 < "%TEMP%\JobBatchMain.R"

rem # Clean up
del "%TEMP%\JobBatchMain.R"

 

To add this automatically to the Windows search PATH, you can call the following in your Windows Command line startup script:

1

    Rterm --slave -e "cat(system.file('bin', package='R.batch'))" > %TEMP%\DIR.tmp
    for /F "delims=" %%G in (%TEMP%\DIR.tmp) do set dir=%%~sG
    IF EXIST "%dir%" (
      echo Detected R.batch package - added to the search path.
      path %PATH%;%dir%
    )
