Hi all,

Maybe a bit late, but I found a way that worked great for me.

In windows, download CutePDF
In linux (debian for me), install CUPS and cups-pdf

Open your pdf with a viewer and print to CutePDF or cups-pdf. Both support a range of compression options. I use cups-pdf and reduced an R output file of 3.6 mb to 0.9 mb. Much better if you want to include in a Latex article

cheers,
Paul
