I have half a solution:
bitmap(file="filename.jpg",type="jpeg"); works to generate a jpeg file.
However, I want my plots to be stored in single jpeg files and I can't get
this to work:
bitmap(file="Rplot%03d.jpg",onefile=FALSE,type="jpeg");
it overwrites my Rplot001.jpg file.
Any one additional comments on how to generate multiple jpeg files?
