&#8230;

Methods to efficiently calculate a matrix trace depending on the class of matrix.

Fit linear mixed-effects models using restricted (or residual)
maximum likelihood (REML) and with generalized inverse matrices to specify
covariance structures for random effects. In particular, the package is
suited to fit quantitative genetic mixed models, often referred to as
'animal models'. Implements the average information algorithm as the main
tool to maximize the restricted log-likelihood, but with other algorithms
available.
