fritty: Forged Data for Metapopulation Analysis

In metapop: Metapopulations and Incidence Functions

Description

Data are fictitious. They were generated using metacycle. However, the patch network is made to resemble the example in Hanski et al. (1994).

Usage

data(fritty)

Format

A data frame with 50 observations on the following 5 variables.

x.crd, y.crd

Coordinates of the patches (locations)

A

Areas of patches

p

Occupancy (0 or 1) in the patches.

p2

Occupancy in the same patches next year.

plot(x.crd, y.crd, asp = 1, xlab = "", ylab = "",
cex = sqrt(A *+ 5), pch = 21, col = p + 1, bg = 5 * p)
)
