Hi:
Until today I was perfectly able to use R, and more specifically, Rcmdr. I
just installed Xfree86 4.7.0 (somehow incompatible with R???)However, since
this afternoon I get the following error after loading Rcmdr:

<Quote>
Loading required package: tcltk
Loading Tcl/Tk interface ... Error in fun(...) :
  Can't find a usable init.tcl in the following directories:
    @TCL_IN_FRAMEWORK@ @TCL_IN_FRAMEWORK@



This probably means that Tcl wasn't installed properly.

Error : .onLoad failed in 'loadNamespace' for 'tcltk'
Error: package 'tcltk' could not be loaded
</Quote>

I have Googled around and I'm confused... I'm running R 2.7.1 on Mac OS X
10.4.11 (Tiger). Any help appreciated.

Kind regards,
Bas
