[R-sig-ME] Bivariate MCMCglmm with repeated measures

[PATRICK, Samantha]

Hi

I running a bivariate GLMM, where both of my response variables have repeated measures.  A dummy data set would look like this:

Individual     Presence    Stage
1                      0                       1
1                      1                        1
1                      1                        2
1                      1                        2
2                     1                         1
2                     0                        1
2                     0                        1
2                     1                         2
2                     0                        2

There are a series of individuals.  For each individual we have measures presence/absence repeatedly during life stage 1 and then again repeatedly during life stage 2.

For a straight forward bivariate model, with a single measure per  individual (or repeated measures during only one life stage), the data could be set up like this:

Individual      Presence stage 1          Presence stage 2

However because I have repeated measures for both stages I am struggling to find out how to code the data so MCMCglmm can run.

Does anyone have any experience with this kind of data structure?  I can’t find anything on the R list.

Many Thanks

Sam
