In ashander/matrixmodels: Tools for analysis of matrix population (models)

Description

Project population growth of all age classes in a stochastic environment after fixed time

Usage

  Project.iid(n.0, matrices, p, t.max, nreps = 100)

Arguments

n.0	initial number in stages
matrices	is a list of matrices or d^2 x s matrix, where d number of stages, s the number of matrixes
p	vector of probabilities for drawing each matrix
t.max	time to stop and compute population size
nreps	number of times to compute

Examples

A1 = matrix(c(0,1,.5,0), nrow=2)
A2 = matrix(c(0,2,.5,0), nrow=2)
A3 = matrix(c(0,7,.5,0), nrow=2)
## d=2 stages, to generating appropriate d^2 by 3 matrix for input...
d = 2
mats = c(A1, A2, A3) # s = 3
dim(mats) = c(d^2, length(mats)/d^2)
Project.iid(matrix(1, d, 1), mats, rep(1/3, 3), 10)
