Lacertid.varcov {PHYLOGR}

Variance-covariance matrix for lacertids from Bauwens and Diaz-uriarte (1997)

Description

Phylogenetic variance-covariance matrix for 18 species of lacertids. It is based on Tree A of Bauwens and Diaz-Uriarte (1997).

Format

The Lacertid.varcov data frame has 18 rows and 18 columns, corresponding to each one of the 18 lacertidspecies; the matrix is the phylogenetic variance-covariance matrix between all 18 species; thus, each entry dij is the the sum of branch segment lengths that species i and j share in common.
