R help - Jun 2003 - using R as a script; getting the output to display on screen

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

The default graphics device in non-interactive use is postscript().

Yes, lots of people do as it is in the README.RW1071:  windows().  Just add
an explicit call to see graphics on-screen.
