Dear list members, I am trying the function ranef from package lme4 and I got the following error warning:

Error en UseMethod("ranef") :
no applicable method for 'ranef' applied to an object of class "mer"
What could be the problem?
Best,

My guess is that you have nlme loaded at the same time.
search()
detach("package:nlme")
If that doesn't work, post the results of sessionInfo().
