rich_club_coeff: Calculate the rich club of a graph

Description

This function calculates the rich club of a graph, both the coefficient \(\phi\) and the nodes that make up this subgraph.

Usage

rich_club_coeff(g, k = 1, weighted = FALSE)

Arguments

g

An igraph graph object

k

Integer; the minimum degree for including a vertex (default: 1)

weighted

Logical indicating whether or not edge weights should be used (default: FALSE)

Value

A list with the following components:

phi

The rich club coefficient, \(\phi\).

graph

A subgraph containing only the rich club nodes.

Nk

The number of vertices in the rich club graph.

Ek

The number of edges in the rich club graph.
