On Windows if you grab Rcmd.bat from http://batchfiles.googlecode.com
and place it anywhere in your PATH then you can do the above like this:

Rcmd BATCH myjob.R

without having to set any paths.  Rcmd.bat and all other batch files
in that collection, are self contained so installation is just a matter of
placing whichever you need anywhere on your path.  Rcmd.bat finds
R by looking into the registry and then runs it.
