In case you were unaware of it, r from littler (which has been around even longer than Rscript) has always propagated its arguments into argv: edd@max:~$ r -e'print(argv)' foo bar biz x=42 [1] "foo" "bar" "biz" "x=42" edd@max:~$ See http://dirk.eddelbuettel.com/code/littler.html and my blog pages on littler at http://dirk.eddelbuettel.com/blog/code/littler/ for more about 'r' and littler; pre-built binaries exist at CRAN for Debian and Ubuntu; and it builds easily on a lot of other OSs.
