I am trying to use the Windows version of R to do the following:
-	Have a Delphi front-end which gets the user input
-	Delphi will produce a R script, do a system call to R to 	
	calculate the statistics.

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.

-	How do one see a graph? A graph is plotted in a window which 
	IMMEDIATELY closes afterwords so that one can't see 
	anything. How can one get the graph to show until user 
	presses a key.

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