problems with R and tckl/tk on Mac OS X

Thanks for catching this question. I'd missed Ingo's original email.

Rcmdr does need X.11 and Tcl/Tk, although it uses the versions that
come with Mac OS 10.4. Hence, as Alex indicates, there is no need to
separately install these.

Ingo, if you can't get it to work using John's link, let me know
where you get stuck.  R-Sig-Mac is an alias dedicated to Mac OS
specific questions.

1.  R-sig-mac is the place to go for these sorts of questions.  This  
issue is being discussed there right now.

2.  The instructions at http://socserv.socsci.mcmaster.ca/jfox/Misc/ 
Rcmdr/installation-notes.html are not correct and will mislead you.

3.  The problems with Tcl/Tk are caused by the nice Aqua GUI.  The  
tcl/tk package or any of its dependencies such as Rcmdr can be built  
on MacOS in one of two ways:
       a.  use the Apple included (in 10.4.x) AquaTk.
       b.  use an X11 version of Tk

Packages built as a. cannot be run from within the R GUI but will  
launch happily from a command line.  The problem is that AquaTk  
thinks it is the only GUI for the app and fights with the R GUI for  
possession of the menu bar and system events.  They will work if you  
run R from a shell instead of the GUI.

Packages built as b. can be run from inside the R GUI.  So this is  
the standard for the CRAN binary distributions.

The current R binary (2.3.1) includes an X11 Tcl/Tk.  Make sure that  
it is installed.
