[R] jpeg in batch mode

[Elizabeth Purdom]

Thanks for the quick reply and sorry that I didn't see the documentation 
that could help me. I actually didn't see anything on the jpeg() help 
pages, or didn't recognize what was there as relating to my problem. I 
will look further on the archives if this plus Henrik's reply is not enough.
Best,
Elizabeth
