Professor Ripley, Thank you very much.
I have used Rscript and it runs fine now. Your help is very much appreciated. Best wishes, Andrew hicks -----Original Message----- From: Prof Brian Ripley [mailto:rip...@stats.ox.ac.uk] Sent: 11 January 2009 01:23 To: Andrew Hicks Cc: r-help@r-project.org Subject: RE: [R] Arguments for Rcmd BATCH I suggested you use Rscript, please do. R CMD BATCH is the Unix-alike notation. Rcmd BATCH is the recommended way on Windows, but R CMD BATCH is also accepted. There is nothing to reproduce here, so here is a simple example. tystie% cat foo.R args <- commandArgs(TRUE) print(args) tystie% Rscript foo.R parms=1:33 [1] "parms=1:33" You can redirect the output as you wish.
