I've got R running on a gentoo server that doesn't have X11 installed. Its
a custom build to keep those dependencies at bay! However, some of my
scripts use the base png() function and ggplot2. But, png uses X11.
A google search suggests using the Cairo package, which works... but
changes the fonts (specifically the size of the font). Adjusting the
pointsize doesn't seem to have much effect.
Aside from tuning the CairoPNG function to make my graphs look right, has
anyone found a good way to avoid the X11 dependency but still use the base
png function?
If anyone has experience with CairoPNG and making it look like the base png
function, id love to hear what you've learned!
Thanks,
Justin
