[R] linear mixed effect model with ordered logit/probit link?

[Spencer Graves]

	  Have you received a reply to this?  I haven't seen one.  I just tried 
several things with RSiteSearch.  Searching for "ordered logit" produced 
70 hits.  One of the first 10 indicate, "The CRAN package MCMCpack has 
at least ordered probit." 
(http://finzi.psych.upenn.edu/R/Rhelp02a/archive/38663.html)

	  I haven't used ordered probits or logits or MCMC, but it would seem 
to me that if MCMCpack has ordered probits, it surely should also be 
able to handle mixed effects.

	  If you would like further assistance from this listserve, I suggest 
you read the posting guide (www.R-project.org/posting-guide.html). 
Doing so might increase the chances of obtaining a useful reply quickly, 
especially if your question includes an extremely simple example in a 
few lines of R code that someone can copy from your email into R and 
test a few ideas in a minute or so.

	  Best Wishes,
