[R] generalized linear model with mixed effects

[Samuel Oman]

Hi,

    I need to fit a general generalized linear model, for observations 
on a response Y which is Gamma-distributed and observed in clusters.  So, if

    E(Y) = mu,

then for a suitable link function f, f(mu) is a (linear) function of 
both fixed and random effects.  Are there R packages or functions which 
fit these models, using either MLE or estimating-equation approaches?

Many thanks,
Sam
