addSUPERNODE: Add supersource and supersink nodes

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

Add supersource and supersink nodes

Description

These nodes will later act as source and sink nodes which initiate and terminate the population flow through the network. More specifically, they are added to the distance matrix with values of zero (for the time being)

Usage

addSUPERNODE(dist, sources, sinks)

Arguments

dist	This is a distance matrix between two sites
sources	vector of site names to be added as sources from the supersource node
sinks	vector of site names to be added as sinks to the supersink node

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)
addSUPERNODE(dist, sources = 1, sinks = nrow(dta))
