Perform a stage-based demographic transition

Description

Perform a stage-based demographic transition

Usage

transition(N, E, alpha, beta, gamma, rand = TRUE, seed = 1L)

Arguments

N	A 3-D array of population numbers for each life stage, over a spatial grid (x, y, class).
E	A 3-D array of environmental data (x, y, variable).
alpha	A matrix of transition intercepts (to, from).
beta	A 3-D array of density dependence effects (to, from, modifier).
gamma	A 3-D array of environmental effects (to, from, variable).
rand	Randomize transitions instead of using matrix multiplication? (Boolean, default = TRUE).
seed	Integer to seed random number generator.

Value

A 3-D array of population numbers for each life stage.
