metafolio (version 0.1.0)

generate_straying_matrix: Generate a matrix of straying proportions within a metapopulation

Description

Generate a matrix of straying proportions within a metapopulation. Based on Eq. 2 in Cooper and Mangel (1999).

Usage

generate_straying_matrix(n_pop, stray_fraction, stray_decay_rate)

Arguments

n_pop

Number of subpopulations.

stray_fraction

Fraction of individuals that stray from a given subpopulation.

stray_decay_rate

Exponential rate that straying decays with distance between subpopulations.
