png() and jpg() devices acting weird.
I experienced a similar problem generating PNGs on linux and found that installing a missing font library corrected the situation. Hope this helps, Avram

I use a CentOS 5.2 VPS to generate graphs through an R web- application. I generate generate both pdf() and png() formats of the graphs. The pdf works just fine and generates perfect pictures. However, the figures generated by the png() (and also the jpg) device are messed up. The weird thing is that it does not generate an error. It does generate a file with a figure of the correct size, but the figures are mostly just white space, or small parts of the actual figure. X11 is not installed on the machine so I have to use type="cairo". I have tried installing and updating cairo, glib2, gtk+ in linux, and installed the R-package "Cairo", but with no result.
