This is useful to integrate the results of community finding algorithms that are not included in igraph.
make_clusters(graph, membership = NULL, algorithm = NULL,
merges = NULL, modularity = TRUE)The graph of the community structure.
The membership vector of the community structure, a
numeric vector denoting the id of the community for each vertex. It
might be NULL for hierarchical community structures.
Character string, the algorithm that generated the community structure, it can be arbitrary.
A merge matrix, for hierarchical community structures (or
NULL otherwise.
Modularity value of the community structure. If this
is TRUE and the membership vector is available, then it the
modularity values is calculated automatically.
A communities object.
