adjacency: Dissimilarity matrix based on connectivity information.

Description

From the data of a network, we build a contiguity matrix. Based on this matrix, we generate a dissimilarity matrix. The matrix contains only 0 or 1, 1 if there is no relationship and 0 if there is a relationship. The network object is a data frame with two columns. The first column contains the elements of the network and the second column contains a list of all other elements related to it. The list is a string consisting of the names of the elements separated by commas (see example).

Usage

adjacency(network)

Value

D

Dissimilarity matrix based on adjacency.

Arguments

network
