[R] jpeg in R for Windows?

[Robert Lundquist]

I have tried to put graphs in jpeg files, but even if a file is produced,
neither the graphics software nor the web browser can open such a file:
"Can't read file header". Any suggestions as to what might cause this? 

BTW, the output would presumably be better as png files, but I don't really
know if I can count on my students' web browsers being able to read this
format. Anyone who knows what browsers *can't* handle png files?
