[R] installing R and Rcmdr onMacOS 10.3.9

[Karla Van Meter]

I have been trying to install the new, patched R 2.1.0a along with the  
Rcmdr on my mac. I got the basic R package installed, but in Project  
Manager, the tcltk package will not install.

  When I downloaded the Rcmdr binary package from the Berkeley site, it  
did not show up on the package installer list until a second attempt,  
but it still does not show up on the package manager list.

On the package manager list, the tcltk package is listed as ''not  
installed'. When I click on it to install, it won't. I tried the  
library(tcltk) command, which failed.

The following is the output from the last command:

 > library(Rcmdr)
Loading required package: tcltk

as.logical(now)) :

I am NOT a developer, but an application-oriented grad student.

I'd appreciate any help that will make Rcmdr work.

Thanks,
