By now It seems nobody have idea.
zz <- gzfile("C:/gzpdftest.gz", "wb")
pdf(file = zz)
plot(USArrests)
dev.off()
close(zz)
produce a file named "3" without any extension in my working directory.
Also I don't have any news on how to gzip the pdf afterward (without using an
external executable).

I have not found an easy way to compress a file on filesystem.
Especially I'd like to compress a pdf from pdf() function/device. Is it
possible to compress It on the flight?
I'd like to do something like:
pdf(gzipconnection())
dev.off()
I guess this boils down to a question I asked some time ago concerning getting
the filename of a pdf() device, as I wanted to create a compressed pdf from the
uncompressed pdf created by R (not "zipping" the pdf).
It does not seem to be possible, at least I did not get any response which I
could use to implement my idea (create my dev.off(), which calls dev.off() and
afterwards compresses the pdf by using the file name).
If you find a solution, please let me know.
Cheers,
Rainer
If It is not possible, how can I create a gzip with the pdf?
Thanks
Daniele A.
