Sorry for being unclear. I am aware of that. My use case is, that
apparently, I have called pdf("somefile.pdf") somewhen during a long
lasting R session.
I tend to have separate R sessions open in parallel
for the project I am working on. So, I can easily have R session open
that run for weeks.
So, when I return to an R session (when I got some additional data, I
was asking for, e.g.) after several days, I do not know what that call
was. And for several reasons, the actual call (pdf("somefile.pdf"))
might not even be visible in my R session.
In that situation, I would like to know, which is the open file for the
current device.
I hope that makes my question clearer.
Regards,
Andreas
