1. I'm trying to use R commander.
2. I have: Mac OS X 10.5.6 (9G66), Kernel Version: Darwin 9.6.0.
3. I have X11: Xquartz 2.1.5 - (xorg-server 1.3.0-apple22) (2.1.5).
4. The R command install.packages("Rcmdr", dependencies=TRUE)  was  
5. I use the instructions shown at http://dataninja.wordpress.com/2006/01/20/r-commander/
6. R and R Commander work fine on my Boot Camp Win XP.
7. R command "library(Rcmdr)" yields the result shown below.
8. QUESTION: how do I get file tcltk on my machine so I can run R  
9. I understand it is supposed to be included with Mac OS X.
10. A file search reveals only tcltk.rb in the Ruby framework of my  
library which I suspect is there because I installed XTools in hopes  
of getting tcltk.
11. I have attempted to load the tcltk package from the R package  
manager. It is disallowed.
12. Thanks for your patience for what must be a tiring question.
