[R] pdf() device uses fonts to represent points - data alteration?

[Thomas Petzoldt]

Hi,

this was my former suggestion but as the RSvgDevice doc says:

"This driver currently does not have any font metric information, so the 
use of plotmath is not supported."

Maybe, the future (or already recent) alternative will be:

library(Cairo)

that can among others also create svg and pdf. While I had some problems 
with a former version, it worked now out of the box and was able to do 
both, algebra (plotmath) and geometry (circles) ;-) in high quality. 
Let's see if there is any other drawback.
