betweeness_centrality: Betweeness centrality

In clementviolet/omnivor: Ecological Networks Analysis

Description

#' Betweeness centrality is a measure of the number of time a node is between pairs of nodes. The value can be normalized by the number, see details for more informations.

Usage

betweeness_centrality(graph, normalized = TRUE, ...)

Arguments

graph	an igraph object.
normalized	logical should the coefficients be normalized? The formula would be: C_{Bnorm} = 2 \times \frac{C_{B}}{(n-1)(n-2)} Where C_{B} is the betweeness coefficent vector and n is the number of nodes.
...	others arguments passed to igraph::betweenness()

Value

numeric a vector containing betweeness centrality coefficients for each node.
