colfun0 {pttstability}

default colonization function

Description

Simulates colonization events - events occur as a binomial random process with probability ilogit(p), and populations are seeded with abundance exp(A).

Usage

colfun0(co, xt)

Arguments

co

a numeric vector of length two (p, A), specifying the logit-transformed colonization probability when abundance is zero, and the log-transformed abundance observed immediately after a colonization event

xt

a number or numeric vector of abundances at time t, before colonization has occurred

Value

a numeric, including number or numeric vector of length xt, with predicted abundances after colonization has occurred
