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
