[igraph] Clique percolation method

[Manuel J. Zetina-Rejón]

Hi,

I know there is no future plan to include the CPM in igraph. So I decide to run the code in http://igraph.wikidot.com/community-detection-in-r#toc0

However, I’m getting the error message:

Error in .Call("R_igraph_create", as.numeric(edges) - 1, as.numeric(n),  : 

  At structure_generators.c:84 : Invalid (negative) vertex id, Invalid vertex id

In addition: Warning message:

In .Call("R_igraph_cliques", graph, as.numeric(min), as.numeric(max),  :

  At cliques.c:192 :directionality of edges is ignored for directed graphs

Any ideas of what is wrong? I’ve tried both directed & undirected graphs, also weighted & unweighted and is not running.  I’m using mac.

Thank you!

Manuel
