Calculation of Modularity for a List of igraph Objects

This function calculates the modularity of a list of networks provided in the ig parameter. Modularity measures the strength of division of a network into modules (communities).

Usage

calc_modularity(ig, ncores = 0, cluster_function = cluster_spinglass)

Arguments

ig

A list of igraph objects for which modularity will be calculated.

ncores

Number of cores used for parallel computation. If set to 0, sequential processing is used.

cluster_function

The igraph clustering function to use, or a function that returns modularity. default cluster_spinglass.

If a network has a 'weight' edge attribute it is used both by the clustering function and to compute the (weighted) modularity of the resulting partition.

Value

A data frame with a column Modularity containing the modularity values for each network.

Details

Note: cluster_spinglass() only works on networks with a single connected component.

Examples

if (FALSE) { # \dontrun{
nullg <- generateERbasal(netData[[1]], 10)
calc_modularity(nullg)
} # }
