adephylo (version 1.1-16)

ungulates: Phylogeny and quantitative traits of ungulates.

Description

This data set describes the phylogeny of 18 ungulates as reported by Pelabon et al. (1995). It also gives 4 traits corresponding to these 18 species.

Format

fission is a list containing the 2 following objects :

tre

is a character string giving the phylogenetic tree in Newick format.

tab

is a data frame with 18 species and 4 traits

Details

Variables of ungulates$tab are the following ones :

- afbw: is a numeric vector that describes the adult female body weight (g)
- mnw: is a numeric vector that describes the male neonatal weight (g)
- fnw: is a numeric vector that describes the female neonatal weight (g)
- ls: is a numeric vector that describes the litter size

Examples

if(require(ape) && require(phylobase)){
## load data
data(ungulates)
tre <- read.tree(text=ungulates$tre)
plot(tre)

## look at two traits
afbw <- log(ungulates$tab[,1])
neonatw <- log((ungulates$tab[,2]+ungulates$tab[,3])/2)
names(afbw) <- tre$tip.label
names(neonatw) <- tre$tip.label
plot(afbw, neonatw) # relationship between traits
lm1 <- lm(neonatw~afbw)
abline(lm1)
x <- phylo4d(tre, cbind.data.frame(afbw, neonatw)) # traits on the phylogeny

## test phylogenetic inertia in residuals
orthogram(residuals(lm1), x) 
}
