signed_modularity for class(x) = 'igraph'

1 2	## S4 method for signature 'igraph' signed_modularity(x, membership, weight = NULL)

`x`	An igraph object
`membership`	Defines vertex membership to determine if vertices are similar. May be provided as a string that matches an attribute of x or a vector of length equal to the number of vertices in the graph.
`weight`	Edge weights. Like 'membership', this argument can be defined as a string matching an edge attribute of 'x' or a vector of length equal to the number of edges, but may also be left as NULL which will return an unweighted modularity estimate.
