[R] fonts not rendering during plot

[George Dietz]

I apologize for not going in to too much detail-I didn't want to confuse people with the gory details of what I'm trying to do (trying to make a portable R installation bundled in to a mac app, among other things).  I am on a mac, Mountain Lion. Anyhow, I figured out the problem was with the paths pango looks uses to search for font configuration files. I solved it by writing a script that sets these paths at run-time.

If this happens to be on a Mac, it may mean your screen fonts are corrupt. You can see their names with: names(quartzFonts()).  Using Fontbook.app will sometimes reveal that there are two copies of one of the screen graphics fonts and that one of them displays as blanks. These should be deleted with Fontbook.app.
