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

Subject: [R] problem with the installation of r commander on a mac

Dear list members,

Im trying to install R Commander under Mac OSX Mountain Lion (10.8.2).
After following all the steps described in the installation notes
(http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/installation-
notes.html), I got this error message:

=====
Loading required package: tcltk
Loading Tcl/Tk interface ... done
Loading required package: car
Loading required package: MASS
Loading required package: nnet
Error : .onLoad failed in loadNamespace() for 'Rcmdr', details:
  call: structure(.External("dotTclObjv", objv, PACKAGE = "tcltk"),
class = "tclObj")
  error: [tcl] invalid command name "tk_messageBox".

In addition: Warning message:
In fun(libname, pkgname) : couldn't connect to display ":0"
Error: package/namespace load failed for Rcmdr
=====

The strange thing is that Ive installed Tcl/Tk and XQuark as
recommended.

Ive also tried uninstalling R, reinstalling the latest version (2.15.1
signed) and all packages, and following the same official steps again.
It didnt work neither.

Could you please help me? R Commander always worked fine on my iMac,
until I updated to Mountain Lion.

Best regards,

Marco

In fun(libname, pkgname) : couldn't connect to display ":0"
suggests that X11 is not running. Note that X11 is no longer part of OS X since Mountain Lion.
