incorporate pedigree into lmer
Jon I think you will find the members of this list helpful, but you have given zero information that we can use to help you with your problem. Please provide a representation of your model and a description of your data. Or better yet, some sample data. I don't have any idea what an "animal model" is (maybe others do), but if you can provide a statistical representation, maybe we can walk you through this. Harold

I would like to solve the animal model using several random effects (e.g. individual (animal) and dominance effects). Also, I would like to infer the additive and dominance relationship matrices (covariance matrices). The function pedigree can set up the pedigree structure, but how do I use it in the lmer function? I have not found any convenient example. Thanks in advance. Best regards, Jon Hallander
