[R] exporting high quality graphics from R in Mac OSX

Nope, sorry, I made a mistake - it's Office vX, native for OSX. I've 
had a look around and found quite a few complaints on the 'net about 
Word X claiming to be OSX native but rendering the image as a scruffy 
bitmap, so I guess this is a Word problem. I don't want to invest in 
the newest version of MS Office, which might do it properly... maybe 
I'll hang on for the Aqua version of Open Office, so I can expunge MS 
from my hard drive.
