mmmIndex: Create Movement Index Matrix

In luke-a-rogers/mmmTMB: Fit Markov Movement Models (MMM) via Template Model Builder

Description

Create Movement Index Matrix

Usage

mmmIndex(n, pattern = NULL, allow = NULL, disallow = NULL)

Arguments

n	integer() Number of areas.
pattern	integer() One of 0: full movement, or 1: direct movement between numerically sequential neighbours only.
allow	integer() matrix() Each row indicates directional movement between a pair of areas indexed from one.
disallow	integer() matrix() As for allow, but specified movement is disallowed.

Value

A square binary matrix with zero diagonal of class mmmIndex

Examples

# Neighbours (default)
mmmIndex(6)

# Full movement
mmmIndex(6, 0)

# Neighbours plus 1-6, 2-5, and 5-2, but not 6-1
allow <- matrix(c(1,6,2,5,5,2), ncol = 2, byrow = TRUE)
mmmIndex(6, 1, allow)

# Full minus 1-6
disallow <- matrix(c(1,6), ncol = 2, byrow = TRUE)
mmmIndex(6, 0, disallow = disallow)
