distance {SpatialAcc}

Distance Matrix Computation

Description

Computes Euclidean or Manhattan distances for all pairs of points between two sets of points.

Usage

distance(m1, m2, type = "euclidean")

Arguments

m1

a vector referring to a set of origin point coordinates

m2

a vector referring to a set of destination point coordinates

type

the type of distance to be computed. Two types are currently supported "euclidean" and "manhattan".

Details

When m1 and m2 are identical, the function is equivalent to the dist function of base R.

Value

A distances matrix in which rows refer to origins and columns refer to destinations.
