[R] Error loading R Commander with version 2.10.1 on MacOS 10.5 or 10.6

Thanks very much, John. Installing that tcltk package is all that is required. It would be nice to make this a part of the download of 2.10.1 as it is wasting a significant amount of time for R Commander users on the Mac.

Dear Dwight,

I've never observed this problem myself, and many people apparently run the
tcltk and Rcmdr packages with R 2.10.1 under Mac OS 10.6 without difficulty.
You can confirm that the problem is with tcltk by trying to load that
package independently of the Rcmdr: i.e., library(tcltk). 

Similar questions have been raised several times, however, on both r-help
and the r-mac-sig lists, including in the last week. The problem is probably
with your installation of Tcl/Tk. See, e.g., Rob Goedman's recent post to
r-help, and the following message from r-sig-mac, which tells you what to
do.: <https://stat.ethz.ch/pipermail/r-sig-mac/2010-January/007008.html>.

I hope this helps (please tell me and the list whether it does).
