  The 'symbols' function can draw circles, as well as a few other things 
- stars, squares, rectangles, boxplots and thermometers.

  Postscript produced with symbols' circles option does produce true 
scalable circles, but I don't think you can have true scalable 
postscript ellipses without some major hacking on R's device driver code!
