Re: [igraph] How to identify negative vertices in graph

[Tamás Nepusz]

Hi,

I gave it a try. But apparently my graph is bipartite:

> is.bipartite(graph)

[1] TRUE

is.bipartite() checks whether your graph is bipartite with *some* mapping of vertices into two groups, but it idoes not check whether the “type” attribute actually reflects the truth or not. So, it can happen that you still have an edge that goes between vertices of the same type.
