I have two questions -
1. I am trying to create R png graphs via cron. I have this part working
using Xvfb (X virtual frame buffer). One problem that I have, though, is
that all the fonts on my graphs get messed up. Anybody have any nija R
commands to make all fonts look great? Anybody have any idea how to fix
this? So far, no luck on Solaris or Linux making the Xvfb fonts look
good.
I was thining of sending an e-mail to the Xfree86 org people. Haven't seen anything
helpful on google so far.
2. I really like the png solution that I have working, above, except for
the fonts. Assumming that I can't get the virtual frame buffer working,
I guess I can switch to bitmap devices. One thing I have noticed, though,
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.)
Thanks,
Tony
