| 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
Bauwens, D., and Diaz-Uriarte, R. (1997) Covariation of life-history traits in lacertid lizards: a comparative study. The American Naturalist, 149, 91-11
