Lacertid.IC {PHYLOGR} | R Documentation |
Independent contrast for Bauwens and Diaz-Uriarte (1997) data set; they are
based on the data in the file Lacertid.Original using the
phylogeny in Buwens and Diaz-Uriarte (1997), Tree A — see Lacertid.varcov
The data frame contains eight columns.
The first seven columns are the (standardized) independent contrasts for the respective variables
—see detailed explanation in Lacertid.Original
. The
final column is
