For scripting, you might want to look at littler (my favorite, http://dirk.eddelbuettel.com/code/littler.html) or (the built-in) Rscript. Combined with the getopt package, this lets you call/pipe stuff in and out of R with the same ease as any other Unix tool. -- Seb ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
