crossNN {bioimagetools}

Compute cross-type nearest neighbor distances

Description

Compute cross-type nearest neighbor distances

Usage

crossNN(dist, n1, n2, w = rep(1, n1 + n2))

Arguments

dist

a distance matrix, the upper n1 x n1 part contains distances between objects of type 1 the lower n2 x n2 part contains distances between objects of type 2

n1

numbers of objects of type 1

n2

numbers of objects of type 2

w

optional weights of the objects (length n1+n2), defaults to equal weights

Value

a (n1+n2) x 2 matrix with the cross-type nearest neighbor distances and weights given as the sum of the weights of the involved objects
