if I copy an x11() graphics device to an eps-file (with dev.copy2eps())
the font in the legend is very large and doesn't fit to the legend box
in the eps-file (same with a postscript file). I'm not sure if this is a
R problem rather than a ghostscript one.
But is there a way to solve this problem in R or depends this on my
ghostscript installation?
System: R Version 1.2.3 on Debian Linux 2.2, ghostscript version 5.10.
This is generally an R problem. When copying from one device to
another, or even when resizing the X11 window, the font scaling
sometimes doesn't come out right. That's hard to avoid if you don't
want the "SAS-effect" where fonts become tall+narrow or wide+low if
you scale x/y differently.
What I ususally do is to set the dimensions on the X11 device so that
they match the desired output as closely as possible, e.g.
X11(height=3.5,width=4.4,pointsize=8)
