Dear Marco,
To provide some background, you and I have corresponded about your problem,
and now at least you appear to have the tcltk package installed. Did you
reinstall R as I suggested?
Have you checked that tcltk is working, following the instructions I sent
you in an earlier email?
I don't believe that the Rcmdr ever calls tk_messageBox directly, but there
is a tk_messageBox() function in tcltk, and you can check whether this is
the source (or a symptom) of the problem by issuing the following commands
in a fresh R session:
library(tcltk)
tk_messageBox(message="test")
That should, as the function name suggests, bring up a Tk message box.
Also I'm not sure what's going on with 'couldn't connect to display ":0"',
which suggests an X-Windows issue.
Finally, I'm moving this discussion to r-sig-mac, where you're more likely
to get knowledgeable assistance.
Best,
John
