ungulates: Phylogeny and quantitative traits of ungulates.

ungulatesR Documentation

Phylogeny and quantitative traits of ungulates.

Description

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

Usage

data(ungulates)

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

Source

Data were obtained from Pélabon, C., Gaillard, J.M., Loison, A. and Portier, A. (1995) Is sex-biased maternal care limited by total maternal expenditure in polygynous ungulates? Behavioral Ecology and Sociobiology, 37, 311–319.

Examples

data(ungulates)
ung.phy <- newick2phylog(ungulates$tre)
plot(ung.phy,clabel.l=1.25,clabel.n=0.75)
ung.x <- log(ungulates$tab[,1])
ung.y <- log((ungulates$tab[,2]+ungulates$tab[,3])/2)
names(ung.x) <- names(ung.phy$leaves)
names(ung.y) <- names(ung.x)
plot(ung.x,ung.y)
abline(lm(ung.y~ung.x))
symbols.phylog(ung.phy,ung.x-mean(ung.x))
dotchart.phylog(ung.phy,ung.x,cle=1.5,cno=1.5,cdot=1)
if (requireNamespace("adephylo", quietly = TRUE) & requireNamespace("ape", quietly = TRUE)) {
  tre <- ape::read.tree(text = ungulates$tre)
  adephylo::orthogram(ung.x, tre)
  ung.z <- residuals(lm(ung.y~ung.x))
  names(ung.z) <- names(ung.phy$leaves)
  dotchart.phylog(ung.phy,ung.z,cle=1.5,cno=1.5,cdot=1,ceti=0.75)
  adephylo::orthogram(ung.z, tre)
}
