[igraph] Need more information about memberships

Hi, Gabor,


Now I want to use the function “igraph-community-to-membership()” to check the community structure results from the merges matrix. It is a pity that I am not very clear about the meaning of related parameters. Could you please tell me more about it?


Suppose there is a graph shown as follow:


The graph seems to have obvious community structure. Then what is the merges matrix built by igraph-community-fastgreedy()? Furthermore, how can I export the two communities (the 4-node complete graph {1, 2, 3, 4} and 3-node complete graph {5, 6, 7}) by reading the output parameters (membership and csize) of function igraph-community-to-membership()?


Thanks a lot!
