[R] PDF Compression

[David Keegan]

Hi,

I am generating a large number of graphs with pdf() and
incorporating them in pdf document using pdflatex.

According to the pdf() help:

   'pdf' writes uncompressed PDF.  It is primarily intended for
   producing PDF graphics for inclusion in other documents, and
   PDF-includers such as 'pdftex' are usually able to handle
   .compression.

But pdflatex incorporates the R graphs without compressing them.
They appear in the final document in cleartext, almost but not identical
to what was generated by R.

I tried the latex settings "\\pdfcompresslevel=9",
"\\pdfobjcompresslevel=3". They reduced the overall size of
the final document slightly, but didn't cause the embedded R
graphs to be compressed.

Can anyone suggest how I can get pdflatex to compress the R
graphs while embedding them? My output files are very big,
and I know they would be substantially smaller if the R
graphs were compressed.

Regards,
David
