Dear Rainer,

You could have a look at ggsave() from the ggplot2 package. I guess that
such an approach to save a plot is easier to combine with a tool like
pdftk.

HTH,

Thierry

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not
ensure that a reasonable answer can be extracted from a given body of
data.

Onderwerp: [R] Getting file name from pdf device?

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
