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

[Marco Mello]

Dear list members,

I’m 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 I’ve installed Tcl/Tk and XQuark as recommended.

I’ve also tried uninstalling R, reinstalling the latest version (2.15.1 signed) 
and all packages, and following the same official steps again. It didn’t work 
neither.

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


Best regards,

Marco
