R help - Jun 2011 - Querying the path separator?

Hopefully this is a pretty easy fix -- I need to have R query the path
separator for some code I'm trying to write (it involves using a
system() call) -- the call requires a path and a wildcard, e.g.:

command="mycommand /path/to/*.files" in the case of unix or,
command="mycommand.exe C:\\path\\to\\*.files" on a windows box

System.which is working correctly, so the "mycommand" vs
"mycommand.exe" part is working fine.  The issue is that the /path/to
should be set to getwd(), but this strips the trailing path separator.
 How do I go about querying the correct path separator for the system,
so I can include it in a paste command (via sep=)?  Thanks!
