nd_hamming: Hamming Distance

In kisungyou/NetworkDistance: Distance Measures for Networks

Hamming Distance

Description

Hamming Distance is the count of discrepancy between two binary networks for each edge. Therefore, if used with non-binary networks, it might return a warning message and distorted results. It was originally designed to compare two strings of equal length, see Wikipedia page for more detailed introduction.

Usage

nd.hamming(A, out.dist = TRUE)

Arguments

A	a list of length N containing adjacency matrices.
out.dist	a logical; TRUE for computed distance matrix as a dist object.

Value

a named list containing

D

an (N\times N) matrix or dist object containing pairwise distance measures.

Examples

## load example data and extract only a few
data(graph20)
gr.small = graph20[c(1:5,11:15)]

## compute distance matrix
output = nd.hamming(gr.small, out.dist=FALSE)

## visualize
opar = par(no.readonly=TRUE)
par(pty="s")
image(output$D[,10:1], main="two group case", axes=FALSE, col=gray(0:32/32))
par(opar)
