directedNET: Only allow the network to flow from source to sink

In KiranLDA/migflow: Calculates the maximum flow through a network

Only allow the network to flow from source to sink

Description

This function replaces the bottom side of the distance network with zeroes. This ensures that everything can only go in one direction. i.e. from code example A to B, A to C, A to D, B to C, B to D and C to D

Usage

directedNET(dist, include_diagonal = TRUE, replaceWith = 0)

Arguments

dist	This is a distance matrix between two sites
include_diagonal	'TRUE' means the diagonal is replaced (such that animals cannot remain in a site) and 'FALSE' means they are not
replaceWith	Replace lower part of distance matrix with e.g. zeros or NAs, default is set to 0

Value

A distance matrix in kilometres between all pairs sites

Examples

dta <- data.frame(Site= LETTERS[1:4], Lat= 1:4, Lon= 5:8, Pop=100:103)
dist <- point2DIST(dta)
directedNET(dist)
