[R-sig-ME] Weighting observations by sampling size in lmer

[Javan Bauder]

I have a data set with which I am running a generalized linear
mixed-effects model using lmer. I have 100 used vegetation plots that
I am comparing with 100 randomly selected vegetation plots. The plots
correspond to different animals including in my study so I am using
animal as a random effect. Many of my used plots were sampled multiple
times (1-10 times). For a plot that was measured, say, five times, I
would like to be able to weight that plot rather than enter its
measurements five different times as five separate plots. I know that
lmer has a weights argument and was wondering if I can use the number
of times a plot was sampled to run a weighted regression analysis with
mixed-effects? I have tried searching the various help forums but have
not been able to make sense of the information out there.

Thank you very much,
Javan
