[R] using R as a script; getting the output to display on screen

[Nick Helseth]

Hello-

I'm trying to run R from the command line using a function as an input; it 
seems to run ok when I use "Rterm --vanilla < name_of_R_function.R" (by ok, 
I mean that it will say that it's reading in the correct items) but the 
graphics won't display on screen.  Do I need to explicitly define an output 
device?  Like "Rterm --vanilla < name_of_R_function.R > 
standard_display_device"?  If that is the case, I don't suppose anyone 
happens to know the name of the screen display device in Windows, do they?  
Or is something wrong with the way I'm calling it.  I've also tried "Rcmd 
BATCH --vanilla name_of_R_function.R" to no avail.  If I've just missed this 
in the documentation and/or mailing list archive, I apologize.

Thanks for your time,
Nick
