[R-sig-ME] Error in UseMethod("ranef")

[Luca Borger]

Hello,

are you using updated versions for lme4, Matrix, R? It works on my machine 
(Windows, see below):

(gm1 <- glmer(cbind(incidence, size - incidence) ~ period + (1 | herd),
+               family = binomial, data = cbpp))

> ranef(gm1)
$herd
