I have data on the success / failure of Wood Warbler nests and wish to examine the data using a GLMM in R. The first few lines of data look like this:

where 'nestid' is the identifier of a particular nest, 'fail' is whether the nest failed or remained active on a particular day and 'pred' is whether the nest was predated on a particular day. The remaining columns are variables that I wish to test.

I have managed to load the MCMCglmm package into R but have so far failed to replicate any of the tests in the tutorials that I have found on the web.

Any help would be hugely appreciated. I'm happy to send the full dataset to anyone if it helps.

Many thanks

Tony
