Lizard behaviour

Description

In a study of lizard behaviour, characteristics of 409 lizards were recorded, namely species (S), perch diameter (D) and perch height (H). Perch means preferred place to settle down (a branch on a tree). The focus of interest is in how the propensities of the lizards to choose perch height and diameter are related, and whether and how these depend on species.

Usage

data(lizard)

Format

A 3–dimensional array with factors diam: "<=4" ">4" height: ">4.75" "<=4.75" species: "anoli" "dist"

Examples


data(lizard)

# Datasets lizardRAW and lizardDF are generated with the following code
#lizardAGG <- as.data.frame(lizard)
#f   <- lizardAGG$Freq
#idx <- unlist(mapply(function(i, n) rep(i, n), 1:8, f))
#set.seed(0805)
#idx <- sample(idx)
#lizardRAW <- as.data.frame(lizardAGG[idx, 1:3])
#rownames(lizardRAW) <- 1:NROW(lizardRAW)
