Dear all,
=20
I found a problem with 'lme4'. Basically, once you load the package 'aod' =
(Analysis of Overdispersed Data), the functions 'lmer' and 'glmer' don't =
work anymore:
=20
library(lme4)
(fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy))
(gm1 <- glmer(cbind(incidence, size - incidence) ~ period + (1 | herd),
              family =3D binomial, data =3D cbpp))
install.packages("aod")
library(aod)
(fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy))
(gm1 <- glmer(cbind(incidence, size - incidence) ~ period + (1 | herd),
              family =3D binomial, data =3D cbpp))

Taking into account that this package is used to perform similar analyses, =
this could be a problem.

All the best
