There have been instances where fonts in the Mac system have become  
replaced by corrupted versions. I had it happen with my Symbol font.   
I wonder if one of your primary fonts used by R (and here I believe  
you would be primarily looking at Courier and Helvetica)  suffered a  
similar fate. When it happened to me I found two entries for the same  
font using Font Book.app. Deleting the one that displayed as blanks  
solved the problem. This is what can be used to determine the current  
fonts used by the quartz device:

 > quartzFonts()
$serif
[1] "Times-Roman"      "Times-Bold"       "Times-Italic"     "Times- 
BoldItalic"

$sans
[1] "Helvetica"             "Helvetica-Bold"        "Helvetica- 
Oblique"     "Helvetica-BoldOblique"

$mono
[1] "Courier"             "Courier-Bold"        "Courier-Oblique"      
"Courier-BoldOblique"
