I've seen the other replies, but thought this might be of interest too:
I hacked a hashbang wrapper so you can start an R script with
  #! /bin/sh /usr/bin/setR
and then invoke it with command-line arguments, which get passed to the
script in a character vector called argv.

See http://www.bgl.nu/~glouis/setR.html if you're interested.  I think
the version displayed has a couple of ampersand-lt; that need to be
changed to < if you use 'save as' rather than cutting and pasting.
