(but then you do read R-help, and I disagree with Berton that
 this should be answered in private only)

I'm really not the expert here,
but John Fox'  RCmdr  relies on R's tcltk package,
and it's true that people can well install R on the Mac without
Tcl/Tk capabilities --- just seen a month ago in a course we taught.

For this reason, John has added instructions (based on help from
Rob Goedman) on how to install things on the Mac :

I think for Berton's question, the only necessary step is

 JFox>>> 1) Install X11.app from Apple Install disks (this is a
 JFox>>> must if you want to use any tcltk-based package with R.app).

I disagree a bit and hence reply to R-help.
