Hi,
I'm trying to build a mixed-effects model in which I'd like to include
either a distance matrix or a phylogenetic tree as a random effect.
The troubles I've had are that:
1. Function lmer() in package lme4 only accepts a data frame column as a
random factor and not a distance matrix.
2. Function MCMCglmm() in package MCMCglmm only accepts a rooted and
ultrametric phylogenetic tree as a pedigree argument while my tree is
neither (and for various reasons I cannot construct one or coerce mine
to be a rooted, ultrametric tree).
Is there any way around it?
I'd appreciate mostly a solution to problem 1.
