compcol: Two-species Competition-colonization Metapopulation Model

Description

This model implements a Levins-type metapopulation model for two species, after Hastings (1980). For use with ode in the deSolve package.

Usage

compcol(t, y, params)

Arguments

t

Argument for time

y

A vector for population 1 and 2

params

Vector or list of parameters

Value

Returns a list of length one, for use with ode in the deSolve package.

Component 1

vector of the state variables, y.
