PHYLOGR (version 1.0.11)

GarlandJanis.varcov: Phylogenetic variance-covariance matrix for Garland \& Janis (1993).

Description

Phylogenetic variance-covariance matrix for the species in Garland \& Janis (1993). Note that the phylogeny is not exactly the same as in Garland \& Janis (1993), but actually corresponds to the more recent phylogeny in Garland et al. (1993).

Format

A matrix with the phylogenetic distance between species; every entry dij is the sum of branch segment lengths that species i and j share in common.
