[R-SIG-Mac] Getting arguments from command line to run a R script

[Prof Brian Ripley]

This is not specific to Mac OS X.

See ?commandArgs and the --args argument to R.

Something that is specific to Mac OS X is that the most convenient way to 
do this is to use Rscript, and I understand that is not installed into the 
standard path on the CRAN binary.  It is I think at

/Library/Frameworks/R.framework/Resources/bin/Rscript

See ?Rscript for how to use it.
