I plan to do something similar.  I will use Tcl/Tk as a user interface
front-end to R.  The program will interact with the user via a Tk user
interface and send the appropriate R commands to R using expect.

Unfortunately, expect runs only on Unix and WinNT, as far as I know.
My platform is Sparc/Solaris.

This wouldn't happen using expect because there would be two processes:
the Tcl/Tk/expect user interface program and a separate R process.
