This function calculates the rich club of a graph, both the coefficient \(\phi\) and the nodes that make up this subgraph.
rich_club_coeff(g, k = 1, weighted = FALSE)
An igraph
graph object
Integer; the minimum degree for including a vertex (default: 1)
Logical indicating whether or not edge weights should be
used (default: FALSE
)
A list with the following components:
The rich club coefficient, \(\phi\).
A subgraph containing only the rich club nodes.
The number of vertices in the rich club graph.
The number of edges in the rich club graph.
