getEdgesIn: Extract Edge Indices from Communities

In alextkalinka/linkcomm: Tools for Generating, Visualizing, and Analysing Link Communities in Networks

Description

This function returns edge indices that belong to certain communities or that are incident upon certain nodes.

Usage

getEdgesIn(x, clusterids = 1, nodes = NULL, all = FALSE)

Arguments

x	An object of class linkcomm or OCG.
clusterids	An integer vector of community IDs. Defaults to community 1.
nodes	A character vector specifying node(s) for which edge indices should be returned. Overrides clusterids. Defaults to NULL.
all	Logical, whether the edges for all communities to which the named nodes belong should be returned. Will have an effect only if nodes is not NULL. If FALSE, edges that are directly incident upon the named nodes will be returned. Defaults to FALSE.

Value

An integer vector of edge indices.
