[R] How to vectorize plot graphic?

[Carl Witthoft]

Off the top of my head,  I'd suggest trying ggsave()  with the extension
".svg" .  I realize that SVG files are not recognized by some image display
apps (Microsoft Windows I'm looking at YOU), but IMHO it's the best choice 
for vectorized images.
