Well, I don't see how most of the above is in any way relevant. What PDF gets generated really depends on the cairo version you are using, not on R. Only most recent versions of Cairo (1.10.x) switched the format to PDF-1.5 and added format restriction functions, they are not available in general. In addition, PDF-1.5 is 8 years old, so whatever tools can't deal with it are seriously out of date.
You have completely missed the point. Have a look at both ghostscript's and libpoppler's bug database: neither's support of PDF *1.4* is complete, and that's what, over 10 years old. And I hope you do not used either of them in any form. TeXLive/Evince/xpdf/kpdf/okular used the latter, and linux-based printing used the former.
