[R] system/system2 command

[Jeff Breiwick]

All,

I had a simple function call I used to open up a dos shell running R under 
Win XP:
system("cmd.exe", wait=FALSE, invisible=FALSE).

This does not work with R 2.12.1 - I get a window that briefly flashes open 
but then disappears. Does anyone know the method to open a DOS command 
window in running R with Win XP? Thank you.
