append to PDF file

I think you are looking for the system() command.

There is the 'pdftk' (PDF tool kit) that you will find on the web that
will do the job.  I have used it to both combine and split out the
pages in the PDF file.

yes, thx. GUI tools like www.pdfsam.org do the job too. But is there a
possibility to append files directly in R. That is to invoke "pdftk" inside
R with a "shellandwait"?

perhaps something like

for (i in ...) {
  ...
  savePlot(filename="temp.pdf", type="pdf")
  exec pdftk temp.pdf final.pdf cat output final.pdf
}
