If you don't mind an extra step between R and LaTeX, you could use  
Inkscape to modify your graphics:
	http://www.inkscape.org/
It is a (very nice!) vector graphics editor which:
- works with SVGs (as produced with the RSvgDevice package)
- imports PDFs (really well in the latest development version)
- is available for free, on most platforms
and
- exports PDFs that nicely integrate in LaTeX documents
- exports PSTricks graphics
Then two roads are opened for you:
1- either get a TTF version of the LaTeX fonts (there are packages  
for this on all linux distros I know, for use with Lyx and you can  
probably find them on the web otherwise) and change all the fonts to  
those once your document is in Inkscape (select all > text and font >  
select the font)
2- or open the document with inkscape and export it to pstricks

I personally use Inkscape on all my R graphics because I find it  
easier and quicker to get decent graphics and R and refine their look  
in Inkscape than to get them perfect in R in one shot ( though with  
ggplot2 things are improving on R's side).

Cheers,
