Re: [igraph] two-mode network in igraph

at this point, I have (first type starts with 100, second type with 200):

when I run this I have an error:

bipartite<-graph.bipartite(vertices, edges, directed=TRUE)
Errore in graph.bipartite(vertices, edges, directed = TRUE) : 
  At bipartite.c:438 : Invalid (negative) vertex id, Invalid vertex id

do you have any hint?
