[R] tcl/tk help

[Jon Loehrke]

I am running R 2.5 on a Mac platform and have a difficulty loading the
Tcl/Tk package.

Specifically:

R>library(tcltk)
Loading Tcl/Tk interface ... Error in fun(...) : couldn't connect to
display ":0"
Error : .onLoad failed in 'loadNamespace' for 'tcltk'
Error: package/namespace load failed for 'tcltk'

Is there an explanation to this problem?  Thank you very much.
