lr_modularity: LinkRank Modularity

In baruuum/btoolbox: random toolbox

Description

Calculates the LinkRank modularity (Kim et al. 2010) of a graph partition

Usage

lr_modularity(g, partition, damping = 0.85, pr_algo = "prpack", weight = NULL)

Arguments

g	a igraph object
partition	a graph partition; should be an integer or character vector of memberships or a igraph::communities object
damping	damping factor (1 - teleportation prob.)
pr_algo	algorithm to calculate Perron vector; should be one of "prpack", "arpack", and "power"; defaults to "prpack".
weight	if NULL and g has a weight edge-attribute, then it is used. If weights is a numerical vector, with length equal igraph::ecount(g), then it will be used even if the object g has a weight edge-attribute. If weight is NA, then no weights will be used, regardless of the attributes of g.
