[R] lmer and weights

[Gasper Cankar]

I'm using R2.8.1 and trying to do some nested modelling using lmer and
weights. When I multiply/divide weights with a constant, variance of
groups intercept changes, but variance of the residual doesn't (using
unconditional model). 

Shouldn't they change equally? Are there any specifications on how to
set weights properly?

Thanks for reply,
