Sorry for interjecting, but I have a burning question. It is a bit off topic, so I apologize in advance.

What is the stance of the R Developers regarding this missing R primitive in PDF? Because of the missing primitive all circles are represented as "O" characters. I have run into problems when trying to import R produced PDF plots into Inkscape for some additional post processing and beautification. As a workaround I currently use the Cairo device to export to PDF (and SVG). But this is a bit heavy. It would be nice to be able to save Inkscape editable PDFs directly from the plot window.

Some other far more important issues that could occur have been raised in a past thread:
http://www.nabble.com/pdf%28%29-device-uses-fonts-to-represent-points---data-alteration--td13034770.html For example the unintentional misrepresentation of data on the plot if font substitution occurs and the points are shifted from their original location.

Is this considered a bug or a feature?

Regards,
TL
