Hi,
A new version of MCMCglmm (MCMCglmm_2.13) has been submitted to CRAN
and should be on-line soon.
NEW FEATURES:
a) Covariance structures for the random effects of the form
kronecker(V,A) where A is some arbitrary matrix can now be fitted.
Previous versions only allowed A matrices defined by a pedigree or
phylogeny, and even then only single phylogenies/pedigrees could be
passed. The A matrices (actually their sparse inverses) are passed via
the argument ginverse.
b) c. 10% increase in speed for phylogenetic and pedigree models.
BUG FIXES:
i) If a column sum of Z was zero the associated term could be
incorrectly omitted from the mixed model equations. This is unlikely
to affect the vast majority of users.
ii) If a prior was specified with too many structures then the
redundant prior structures were ignored. An error message is now issued.
iii) MCMCglmm failed with a cryptic error message if the internal
nodes of a phylogeny were labelled but not uniquely. A more helpful
error message is now given.
Cheers,
Jarrod
