Hi, all,

yesterday I ran a GLMM with the glmer function from the lme4 package, 
and extracted the modes of the random effects using ranef(model). This 
morning I tried to do the same and got the following error:

Error in UseMethod("ranef") :
   no applicable method for 'ranef' applied to an object of class "mer"

I tried the example from the R documentation,

fm3 <- lmer(diameter ~ (1|plate) + (1|sample), Penicillin)
ranef(fm1)

and got the same error. It seems that I am missing something. Any clue?

Thanks,

Gustavo S. Betini
