That doesn't work for me using the ancient version of R (a year old)
on this box.  It produces a file that looks like a postscript file,
but which is slightly smaller than the one that a call to pdf() makes
but cannot be displayed by any file viewer I have.

However, it kind of works if I convert the pdf file into a postscript
file using pdftops, but I doubt that's what Jinsong wanted.  It's
35Mb!

Perhaps it really does work using a more up to date version.
