R help - Jan 2006 - Including random effects in logistic regression.

I'm trying to analyse some data using logistic regression in R, but I 
want to include random effects in the model.  The glm function 
appears not to have options for including random effects, and the lme 
and nlme documentation indicates that these functions are for 
continuous, not dichotomous, response variables.  Are there options 
in R for this type of analysis?

Jason

the lmer() function in the Matrix package is what you will need.
