R help - Mar 2009 - How to set R_PROFILE conditional on batch or interactive mode

I am running R 2.8.1 on SUSE Linux. I would like to be able to set
R_PROFILE to two different possibilities. One when R is called by R CMD
BATCH and another any other time. Is this possible?

I think so.  In your .Rprofile have code like unto:

	if(interactive()) {
		# Do the non-batch thing
	} else {
		# Do the batch thing.
	}

Haven't tested this, but.

Hmmm.  Try:

cargs <- commandArgs()
mmm   <- match("-f",cargs)
if(is.na(mmm)) {
	# Do the non-batch thing.
} else {
	# Do the batch thing.
}

Does that get you where you want to go?
