make_dispersal_multiplier_matrix: Make a default matrix of relative dispersal probabilities between areas

Description

Given either a list of areas, or a list of states, this function provides a square dispersal matrix giving the relative probability of dispersal between areas. The function fills in these dispersals probabilities with the value 1. The user can then modify this as desired. dispersal_multipliers_matrix Default NULL distances_mat Default NULL x_exponent Default 0

Usage

make_dispersal_multiplier_matrix(areas = NULL, states_list = default_states_list(), dispersal_multipliers_matrix = NULL, distances_mat = NULL, x_exponent = 0)

Arguments

areas

A list of areas; if NULL, the states list will be used.

states_list

A list of states, where each state consists of a list of areas. A default example list is provided.

dispersal_multipliers_matrix

Default NULL.

distances_mat

Default NULL.

x_exponent

Default 0.

Value

dispersal_multiplier_matrix A square matrix, with 1s for all cells.

Details

If only a states list is given, the list of areas is calculated by getting unique values from the concatenated states list.
