[igraph] graph.knn in R

[Umberto77]

Hi,

I've got probblems with gaph.knn in R using a weighted directed graph. It is supposed to ignore directions isn't it?

that's what I've got/

> graph.knn(g, vids=V(g), weights=TRUE)

Errore in graph.knn(g, vids = V(g), weights = TRUE) : 

  At structural_properties.c:6493 : Average nearest neighbor degree Works only with simple graphs, Invalid value

thanks a lot!
