Hi - I'm having a problem trying to use the function GLMM() from lme4. Here
is what happens:

 

> library(lme4)

Loading required package: Matrix

Loading required package: lattice

> f1 <- GLMM(success~yearF, data=quality, random=~1|bandnumb,
family=binomial, method=PQL)

Error: couldn't find function "GLMM"

 

I remember having used lme4 before, without any problem. Can someone help me
understanding what is wrong? I'm using R 2.2.1, could that be a problem? I
also tried installing lme4 again, and updating the package, with no success.

 

Thanks for your help,

 

Amelie
