Calculate net migration from an origin-destination migration flow matrix.

Description

Sums each regions flows to obtain net migration sums.

Usage

sum_net(m, region = 1:dim(m)[1])

Arguments

m

Matrix of origin-destination flows, where the first and second dimensions correspond to origin and destination respectively.

region

Integer value corresponding to the region that the net migration sum is desired. Will return sums for all regions by default.

Value

Returns a numeric value of the sum of a single block.
