Nick, You don't specify OS, so details might differ, but on my linux system the help for system (which should be the first place you'd look anyway) has an entire section on stdout and stderr
Stdout and stderr: Error messages written to ‘stderr’ will be sent by the shell to the terminal unless ‘ignore.stderr = TRUE’. They can be captured (in the most likely shells) by system("some command 2>&1", intern=TRUE) What happens to output sent to ‘stdout’ and ‘stderr’ if ‘intern = FALSE’ is interface-specific, and it is unsafe to assume that such messages will appear on a console (they do on the Mac OS X console, but not on some others).
