IsaacEtAl {caper}

Example dataset for the caper package

Description

This data set contains four species-level comparative datasets used in Isaac et al (2005)

Usage

data(IsaacEtAl)

Format

The datafile contains species level phylogenies and accompanying data frames of nine variables for each of four mammalian orders (Primates, Carnivora, Chiroptera and Marsupialia). The data were published in supplementary material for Isaac et al. (2005) as CAIC format files and text data files and have been converted for use in 'caper'. The data files are incomplete, with some variables having little or no data for some orders.

The variables (all saved as natural log values) are:

species.rich

Species richness at the tips - all are set to 1 for use in macrocaic

body.mass

The average body mass in grams

age.sexual.maturity

Age at sexual maturity in months

gestation

Gestation length in days

interbirth.interval

Interbirth interval in months

litter.size

The average number of offspring in a litter

population.density

Population density

group.size

Number of individuals in a typical group

mass.dimorphism

Male mass /female mass

length.dimorphism

Male length / female length
