[R-sig-ME] weights in lmer

[Sundar Dorai-Raj]

Hi, Prof. Bates,

It appears the weights argument is ignored in lmer but not in lmer2. 
See, for example:

library(lme4)
set.seed(1)
w <- abs(rnorm(nrow(sleepstudy)))
fm1 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy)
fm2 <- lmer(Reaction ~ Days + (Days|Subject), sleepstudy, weights = w)
fm3 <- lmer2(Reaction ~ Days + (Days|Subject), sleepstudy, weights = w)
VarCorr(fm1) # no weights
VarCorr(fm2) # same as fm1, incorrect
VarCorr(fm3) # `w' applied correctly
