Hi Uwe,
Thanks. At this point I need solve one doubt:
If I use windows(width=8.27, height=11.69, rescale="fixed"), it shows the
content in graphics window as real size, and a vertical scroll appears. How can I get it
in Mac and Linux?. I mean, how can I get it in quartz() and X11()?.
Moreover, I would need to identify in runtime the operating system and screen resolution,
in order to know if I have to use rescale="fixed" or not. And I don't how to
detect it.
See ?dev.new, ?.Platform and ?dev.size, and on a non-Windows box ?X11
and ?quartz. The 'screen resolution' isn't an unambiguous concept (some
screens have non-square pixels, for example) and is not available
directly at R level. I do not see why you need it. For an open
graphics device comparing graphical parameters 'cin' and 'cra' may come
close, but it is notional (you will get 72ppi on all Macs regardless of
the hardware).
Note that your original question only makes sense on Windows: there is
no 'copy to pdf' menu on X11(), and there is no resizing to fit on
screen on quartz(): I just tried and A4 plot and the 'Save' menu item
and it worked.
And on Windows the re-sizing only occurs when actually plotting: copying
the plot to pdf replays the original plot instructions.

Eva

Hi Uwe,
Thank you for your help. Then, how can I know (in runtime) then max
width and height I can use?. If it depends on the screen inches, I
should obtain those values in runtime, is this true?.
The appearance in graphic window must be vertical (as A4 paper or
something like that), apart from the fact that the result of pdf created
must be the same as A4 paper.
Well, since it rescales, I'd just open the screen as you proposed and use
dev.print(pdf, file="test.pdf", width=8.27, height=11.69)
or whatever afterwards to copy *iff* you do not want to use the pdf
device directly, which is recommended.
Best,
Uwe Ligges

Correctly: yes, but not as you expect. It keeps the aspect ration
but in
a smaller size if the screen is smaller than the size you specified.

Yes.

Why not use pdf() directly?
Anyway, you can
dev.print(pdf, file="test.pdf", width=8.27, height=11.69)
