Logical scalar, whether to return the merge matrix.

modularity

Logical scalar, whether to return a vector containing the
modularity after each merge.

membership

Logical scalar, whether to calculate the membership vector
corresponding to the maximum modularity score, considering all possible
community structures along the merges.

weights

If not NULL, then a numeric vector of edge weights.
The length must match the number of edges in the graph. By default the
‘weight’ edge attribute is used as weights. If it is not
present, then all edges are considered to have the same weight.
Larger edge weights correspond to stronger connections.

Value

cluster_fast_greedy returns a communities
object, please see the communities manual page for details.

Details

This function implements the fast greedy modularity optimization algorithm
for finding community structure, see A Clauset, MEJ Newman, C Moore: Finding
community structure in very large networks,
http://www.arxiv.org/abs/cond-mat/0408187 for the details.
