> I mean I can traverse and change the label of any node in that network. This can be done by manipulating the "label" attribute of a node. Nodes can be accessed by indexing the "vs" vertex sequence of the graph. E.g.:
graph.vs[1]["label"] = "new label" Edges can be manipulated similarly by indexing the "es" edge sequence: graph.es[1]["weight"] = 42 > For example, node 0 has two neighbors 1 and 2.

Please take a look at the add_edge(), add_edges(), delete_edge() and delete_edges() method of the Graph object in the documentation: http://igraph.sourceforge.net/doc/python/igraph.Graph-class.html#add_edge http://igraph.sourceforge.net/doc/python/igraph.Graph-class.html#add_edges http://igraph.sourceforge.net/doc/python/igraph.Graph-class.html#delete_edges Members of the edge sequence also have a delete() method: graph.es[1].delete() By the way, out of curiosity, why do you import the igraph module using the alias "nx"? "nx" usually refers to the NetworkX module. -- T. _______________________________________________ igraph-help mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/igraph-help
