[igraph] graph.knn in R weighted vs unweighted

[Umberto77]

Dear Gabor,

I am dealing with a network of trade relationships, where the edges' weights correspond to the value exchanged.

When running graph.knn there is no difference both in the knn and the knnk values comparing:

graph.knn(graph, weights=NULL)

and

graph.knn(graph)

Am I loosing something?

Thanks, Umberto Medicamento
