Hi Class,
I was having issues getting CEM to run on my MAC over the weekened,
which ended up prompting a email chain with our TFs, Gary, and one of
Gary's co-authors. We finally figured out the issue, and Molly
suggested that I sent out the solution to the class because she also
had the same thing happen when trying to use CEM on her MAC.
Essentially the issue is that after running "library(cem)", using any
commands that required CEM would result in R freezing and the mac
colorwheel would just keep going when trying to use R.
The solution to this problem is to download the latest version of R,
2.12.2 from
http://software.rc.fas.harvard.edu/mirrors/R/ (I had only
downloaded R on this computer at the start of this semester, and this
version is new since then). Then after that has downloaded, to go to
the development tools section of the cran website
(
http://software.rc.fas.harvard.edu/mirrors/R/) and download
tcltk-8.5.5-x11.dmg. After both of those things are downloaded, when
you run R, before you load CEM, you have to run "library(tcltk)".
After that, if you then run "library(cem)" everything will work fine.
Anyway, hope this helps for anyone else that has a MAC and is having issues.
Adam
