[R] Journal Quality R Graphs?

[Werner Wernersen]

Hi!

I have browsed the help archives but did not find
anything on the subject: How 
to make publication quality graphs with R best?
Is there some document about that topic out there? The
problem is that the 
graphs look nice on the screen but when printed in
black and white every color 
apart from black doesn't look very nice. Is there some
guideline how to set 
color palettes and or fill patterns for charts?

Thank you very much for considering my question in
advance.

Best,
   Werner
