Hello,
I have count/proportion data and I am trying to account for overdispersion
in a logistic regression. With the following code from lme4 I receive the
following error message:

> glmm = glmer(cbind(fertilized, unfert) ~ density.class + (1|individual),
family = binomial)
Number of levels of a grouping factor for the random effects
is *equal* to n, the number of observations

This problem was mentioned in Warton and Hui 2011, so I imagine it may have
been fixed recently.  I downloaded the most recent version of lme4 available
through the command install.packages("lme4").  Is there an updated version
of the package available in a different form?

I am using R version 2.13.1 on OS 10.6.4.

thank you!
Gabrielle
