Example dataset for the CAIC package

Description

This is a comparative dataset on Perissodactyla taken from the examples include with the original CAIC program.

Usage

data(shorebird)

Format

The datafile contains a phylogeny (perissodactyla.tree) of 18 perissodactyl species as a 'phylo' object from the ape library. The tip names are the binomial names of the species. The file also contains a data frame (perissodactyla.data) of variables 5 variables for 13 of those species:

Binomial

The species binomial name.

log.female.wt

Log female weight

log.gestation.length

Log gestation length

log.neonatal.wt

Log neonatal weight

Territoriality

A factor indicating whether or not the species displays territorial behaviour.

The dataset is incomplete - it does not include data for each species in the phylogeny and contains missing values. See the examples for the behaviour of the 'comparative.data' function in handling missing data.

data(perissodactyla)
# default behaviour is to omit incomplete data rows
(perisso <- comparative.data(perissodactyla.tree, perissodactyla.data, Binomial))
# but this can be turned off
(perisso <- comparative.data(perissodactyla.tree, perissodactyla.data, Binomial, na.omit=FALSE))
na.omit(perisso)
