I have played with Xvfb and have not seen the same font problem (Mandrake 9.0 for Linux, R 1.6.2) generating png's via CGI (my problems are more with CGI-secure permissions). You mentioned running a cron (batch) job -- do you see the same problem using R interactively (such as an ssh login with X not running)? Perhaps you can provide some lines of your code of your cron script to help the diagnosis? What is specifically messed up with the fonts? Adjusting the pointsize argument in png might help. > is that the bitmap files are enormous compared to the png images. Any > idea how I could make the bmp images smaller (and create > faster?) (One of > my R bmp generation files is attached.) As far as bitmaps go, I think that in general the smaller they are, the less resolution you will have. But even if you are willing to give that up, you might need to delve into ghostscript call options, since my understanding is that what bitmap() uses under Linux (and I presume other X11 device approaches including Solaris). See the code for bitmap(), in particular the gsexe and cmd objects. (I noticed your setting of some arguments like res in your bitmap generation file attachment, but as I guess above, other gs-intrinsic flags may be needed.)
