centr_betw: Centralize a graph according to the betweenness of vertices

In igraph: Network Analysis and Visualization

Centralize a graph according to the betweenness of vertices

Description

See centralize() for a summary of graph centralization.

Usage

centr_betw(graph, directed = TRUE, normalized = TRUE)

Arguments

graph	The input graph.
directed	logical scalar, whether to use directed shortest paths for calculating betweenness.
normalized	Logical scalar. Whether to normalize the graph level centrality score by dividing by the theoretical maximum.

Value

A named list with the following components:

res	The node-level centrality scores.
centralization	The graph level centrality index.
theoretical_max	The maximum theoretical graph level centralization score for a graph with the given number of vertices, using the same parameters. If the normalized argument was TRUE, then the result was divided by this number.
