EDIT:

Okay, it seems that X11 renders the fonts etc...okay

Typing in:

X11()
demo(plotmath)
dev.off()

seemed to render everything including the fonts fine, so I don't think any of my fonts are corrupted.

But is there a way to configure R to set X11 as the default device for graphics? Right now, it uses quartz as its default device for rendering to the screen. I'm a bit of a newbie here, so could somebody explain how to add to my R config file to have the default device be X11?

For most men life is a search for the proper manila envelope in which to get themselves filed.
