R help - Jan 2003 - Problem with pdf()

Hallo,

I noted the PDF format of pdf() beeing PDF-1.1.
I would like to know if it is possible to generate PDF files in PDF-1.2.
For some strange reason it is not possible to visualize certain pdf files
generated via R on IE 5.5 (using AR 5.1).
But converting this to PDF-1.2 (using postscript() and gsv), it works.
It would be nice to test with pdf() generating a PDF-1.2 file, just to confine
the problem.

Thanks for any help,

A PDF-1.1 file is a PDF-1.2 file.  They are backwards compatible 
specifications.

The source code is available to you if you want to re-write the driver to
make use of features in, say, PDF-1.2 or even the current 1.4.
