FOMD (Fraction Over Median Degree)

Description

Given a weighted graph and a partition into communities, returns the fraction of nodes of each community whose internal degree (i.e. the degree accounting only intra-community edges) is greater than the median degree of the whole graph.

Usage

FOMD(g, com, edgelist = NULL)

Arguments

g

Graph to be analyzed (as an igraph object). If the edges have a "weight" attribute, those will be used as weights.

com

Community membership integer vector. Each element corresponds to a vertex.

edgelist

alternatively, the edgelist of the graph, as a matrix where the first two columns to the vertices and the third is the weight of each edge.

Value

Numeric vector with the FOMD of each community.
