[R] Getting file name from pdf device?

[Rainer M Krug]

Hi

IU would like to modify the dev.off function, so that it automatically
compresses the created pdf.
I am thinking of doing the following in the modified dev.off:

1) Get the filename of the pdf device
2) close the device by calling the original dev.off()
3) compress the pdf file with a system call of pdftk.

My question: how can I get the filename of the pdf from the device
before it is closed?

Thanks

Rainer
