dist_sim_matrix: Structural similarities

In anespinosa/netmem: Social Network Measures using Matrices

Structural similarities

Description

In the literature of social network, Euclidean distance (Burt, 1976) or correlations (Wasserman and Faust, 1994) were considered as measures of structural equivalence.

Usage

dist_sim_matrix(
  A,
  method = c("euclidean", "hamming", "jaccard"),
  bipartite = FALSE
)

Arguments

A	A matrix
method	The similarities/distance currently available are either Euclidean (default), Hamming, or Jaccard.
bipartite	Whether the object is an incidence matrix

Value

This function returns a distance matrix between nodes of the same matrix.
