X11 problem after migration to Leopard

Martin,

as per posting guide you have forgotten all of the very important
piece of information - R version and the locale. I cannot reproduce
the problems you describe, so please share with us at least the output
of sessionInfo().

In general, if you want to use X11 on Leopard seriously, you may want
to upgrade it (see http://trac.macosforge.org/projects/xquartz ),
because the version shipped with Leopard is known to be quite broken.

Cheers,
Simon

Hi,

After migrating to Leopard I have problems with X11 when sunning R
from the command line (which I prefer). I acknowledge that this most
likely is not an R issue, but I thought that somebody else on this
list might have had the same problem and has a nice solution to
offer...

When trying to plot something in R from the command line (it works
however from the R GUI) I get the following error message:

===========================================
Error in X11() :
 could not find any X11 fonts
Check that the Font Path is correct.
In addition: Warning messages:
1: In X11() :
 locale not supported by Xlib: some X ops will operate in C locale
2: In X11() : X cannot set locale modifiers
===========================================

So, it seems like R cannot find the fonts. Issuing xset -q in the
terminal generates the following output:

===========================================

To me the font path in this output seems correct.

I have disabled all DISPLAY settings that I previously had in
my .bash_profile and my PATH variable is set according to: export
PATH=
$PATH:/usr/local/bin:/Applications:/usr/X11/bin:/usr/X11/lib:.

Any suggestions about how to fix this problem is greatly appreciated!

Thank you very much!

Best regards,

Martin.
