## Phylogeny and quantitative traits of lizards

### Description

This data set describes the phylogeny of 18 lizards as reported by Bauwens and Díaz-Uriarte (1997). It also gives life-history traits corresponding to these 18 species.

### Usage

    data(lizards)

### Format

`lizards` is a list containing the 3 following objects :

traits
  is a data frame with 18 species and 8 traits.
hprA
  is a character string giving the phylogenetic tree (hypothesized phylogenetic relationships based on immunological distances) in Newick format.
hprB
  is a character string giving the phylogenetic tree (hypothesized phylogenetic relationships based on morphological characteristics) in Newick format.

### Details

Variables of `lizards$traits` are the following ones : mean.L (mean length (mm)), matur.L (length at maturity (mm)), max.L (maximum length (mm)), hatch.L (hatchling length (mm)), hatch.m (hatchling mass (g), clutch.S

### Examples

    data(lizards)
    w <- data.frame(scalewt(log(lizards$traits)))
    par(mfrow = c(1,2))
    wphy <- newick2phylog(lizards$hprA)
    table.phylog(w, wphy, csi = 3)
    wphy <- newick2phylog(lizards$hprB)
    table.phylog(w, wphy, csi = 3)
    par(mfrow = c(1,1))
