Use this if you are using igraph from R
Find community structure that minimizes the expected description length of a random walker trajectory
cluster_infomap( graph, e.weights = NULL, v.weights = NULL, nb.trials = 10, modularity = TRUE )
graph |
The input graph. |
e.weights |
If not |
v.weights |
If not |
nb.trials |
The number of attempts to partition the network (can be any integer value equal or larger than 1). |
modularity |
Logical scalar, whether to calculate the modularity score of the detected community structure. |
Please see the details of this method in the references given below.
cluster_infomap
returns a communities
object,
please see the communities
manual page for details.
Martin Rosvall wrote the original C++ code. This was ported to be more igraph-like by Emmanuel Navarro. The R interface and some cosmetics was done by Gabor Csardi csardi.gabor@gmail.com.
