new R packages for phylogenetic compartive methods
...ificantly beyond the Brownian motion (BM) and Ornstein-Uhlenbeck (OU) processes.
1) There is a new version of mvSLOUCH available. The most important change is that
the inference engine has been completely rewritten. Instead of directly evaluating the multivariate normal density formula it uses the PCMBase (R package, see below) to obtain the value of the likelihood in linear (in number of tip species) instead of quadratic time. Furthermore, as there is no need to store the between-species-between-traits variance covariance matrix much larger clades, then previously can be handled. From the user'...
