compute_modularity: Function to compute citation graph modularity over a time...

In Diderot: Bibliographic Network Analysis

Description

This function computes Newman's modularity of the citation graph restricted to a given time window and ignoring nodes belonging to both corpora simultaneously.

Usage

compute_modularity(gr, infLimitYear, supLimitYear)

Arguments

gr	Citation graph
infLimitYear	Start year of the time window considered (included)
supLimitYear	End year of the time window considered (*excluded*)

Value

Returns Newman's modularity value of the subgraph restricted to the interval [infLimitYear;supLimitYear[.
