[R] Importing vector graphics into R

[Hinrich Göhlmann]

Dear R users,

I know of the possibility to import bitmaps via the nice pixmap library. 
    But if you later on create a PDF it is somewhat disappointing to 
have such graphics bitmapped. Is there a trick (via maps?) to import a 
vector graphic and have them plotted onto a graph? My searching attempts 
in the searchable r-help archive did not seem to result in anything 
useful...

Cheers,
