Hi,
I am running a MacBook Pro with OS X 10.6.8. When I try to load library(cem)
and run any function, R crashes. Any suggestions as to why this is? Thanks in
advance. I think the problem is that I don't have all the "infrastructure" I
need to run CEM, but I have no clue what to do either...
#Do I have tcltk (I have no clue what that is)
capabilities("tcltk")
tcltk
TRUE

This probably means that tk wasn't installed properly.
