Dear Simon,
Thank you for your replies, I understand now your explanation about R.app.
I do not think that the topic on the locale is unrelated to the plot
problem, since adding to .bashrc:
export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
does solve the problem with plot(), as you can see from the following
output:
> Sys.getenv("DISPLAY")
[1] ":0"
> sessionInfo()
R version 2.14.1 (2011-12-22)
Platform: x86_64-apple-darwin9.8.0/x86_64 (64-bit)
locale:
[1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8
attached base packages:
[1] stats graphics grDevices utils datasets methods base

It is still not clear to me why I need to add above lines to .bashrc,
since on my Snow Leopard machine this is not necessary. The locale there
is also only C.
BTW, to run R I start always X11.app first and then start R from xterm,
I do not use the Terminal.
Best regards
Christian

Yes, although I have started X11.app and run R from within an xterm I get:

No protocol specified
Error in X11(d$display, d$width, d$height, d$pointsize, d$gamma, d$colortype, :

In addition: Warning message:

Chances are that you DISPLAY is unset - you possibly messed with it in your
startup files so R can't use X11 unless you give it the proper display. On a
clean OS X you will see it set properly, e.g.:
Sys.getenv("DISPLAY")
[1] "/tmp/launch-byCZTH/org.x:0"
Please check that your DISPLAY is set (and that you don't mess with R options,
either). This is setting is automatic on SL/Lion.
Cheers,
Simon

I have never had this problem on Snow Leopard, Leopard or Tiger!
Does someone have an idea what might be the reason?
