Hi list,
When exporting to PDF a graph with a legend, in the final PDF, the text
is going beyond the legend box.
> dev2bitmap("test.pdf", type="pdfwrite", h=6, w=6)
The legend looks OK on the screen.
I noticed that the size of the legend box depends on the size of the
screen window, which is not the case for other graphical parts (text of
the legend, title, axis text...)
Any tip on how to deal with this?
Another problem I encounter, which may be linked to this is:
When I want to export PDFs to a given size with dev2bitmap (let's say
h=3 and w=3), the size of the text of x-labels, y-labels and the x-axis
annotations is not adjusted. The margins also keep the same size. Then
if the size is too small, all the text fields overlap and the result is
not nice.
How to change this? I guess it's possible since the on the screen (x11)
the margins are adjusted relative to the size of the plot.
If you know one good tutorial to help creating ready-to-publish
graphics, I would appreciate the reference.
Thanks for your help
Julien

I'm sure someone more familiar wiht the internals will comment on this. The fix is easy: don't use dev2bitmap but open the desired target device before plotting. In your case: pdf(file='test.pdf', width=6, height=6) plot(...) legend(...) dev.off() cu Philipp -- Dr. Philipp Pagel Lehrstuhl f?r Genomorientierte Bioinformatik Technische Universit?t M?nchen Wissenschaftszentrum Weihenstephan 85350 Freising, Germany and Institut f?r Bioinformatik und Systembiologie / MIPS Helmholtz Zentrum M?nchen - Deutsches Forschungszentrum f?r Gesundheit und Umwelt Ingolst?dter Landstrasse 1 85764 Neuherberg, Germany http://mips.gsf.de/staff/pagel
Copying between devices (as in dev2bitmap) is not a good way to produce
high-quality graphs, and especially not if you change the size.
What is wrong with
pdf("test.pdf", width=6, height=6)
< re-run the plot commands>
dev.off()
?

With R version 2.7.0 you have other possibilities, including
dev.copy2pdf() and quartz(type="pdf").
