I had the same problem and my conclusion was also that the problem was that our server was not running an X server. I also found that bitmap(file="filename.jpg",type="jpeg"); works.. However I want to store my plots in single jpeg files.. Unfortunately bitmap(file="Rplot%03d.jpeg",onefile=FALSE,type="jpeg" does not work for bitmap()..
Any ideas on how to generate multiple jpeg files from my plots/ etc ?
