R help - Apr 2013 - fonts not rendering during plot

Hi,

I am having a problem where sometimes fonts for text in plots don't get
rendered-the text just shows up as boxes. If I call R from a certain directory
the problem goes away, otherwise the fonts don't render (but plots get
made). In both cases, my PANGO_RC and FONTCONFIG_FILE do not change?

Thank you,
-George

Offering the OS details is more courteous than omitting them. (And there are
several other courtesies expected of you listed in the Fine Posting Guide.) 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.
