Here's one thing to add to the discussion of how mcmcsamp affects lmer
objects (discussion by Rabagliati, Frank, and Bates): the changes that
mcmcsamp makes to the lmer object result in crashes when one attempts to
apply aovlmer.fnc to the lmer crashing, producing error messages (see,
e.g.,
http://www.nabble.com/Problem-with-aovlmer.fnc-in-languageR-td20706128.html
). I had corresponded with Harald Baayen, who verified the problem, and
noted that the p values returned by current versions of mcmcsamp may not
be the same as those returned by older versions. I am delighted that Dr.
Bates is now aware of the problem.
