Dear Patrick,

You can fit such a model with the MCMCglmm package. Have a look at the vignette of that package.

install.packages("MCMCglmm")
vignette("CourseNotes", package = "MCMCglmm")

But I'm affraid that this will require some rockclimbing upon the learning curve if you are a R novice.

HTH,

Thierry

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.
~ Sir Ronald Aylmer Fisher

The plural of anecdote is not data.
~ Roger Brinner

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
