LinkDensities function

Calculate Link Community Link Densities

This function calculates link densities for link communities.

LinkDensities(x, clusterids = 1:x$numbers[3])

Arguments

• x: An object of class linkcomm.
• clusterids: An integer vector of community IDs. Defaults to all communities.

Details

The link density of community i is

where $e_{i}$ is the number of edges in community i and $n_{i}$ is the number of nodes in community i.

Returns

A named numerical vector, where the names are community IDs and the numbers are link densities.
