R help - Mar 2009 - Executing an external executable from within R?

For example, from within an R script I would like to be able to launch
NotePad.exe.

Is there an R call for launching Notepad.exe from within R? 

I've tried the following, but they don't seem to
work:
> system(paste('"C:/WINDOWS/NOTEPAD.exe"'), wait = FALSE)
> system("C:/WINDOWS/NOTEPAD.exe", wait = FALSE)
> system("NOTEPAD", wait = FALSE)
That is, these do not bring up the Notepad GUI.  

Thanks for any insights.

Dear Jason,
Try this:

shell.exec('C:/WINDOWS/NotePad.exe')

HTH,

Jorge

shell("notepad")

works for me. I am using Windows Vista.
