it seems that i have to add each vertex and edge by myself, and add a "type" property for the vertices, because the seller id and buyer id both are numbers, igraph can not distinguish them...

????: [igraph] bipartite from edgelist?
i have some order records including buyer ids and seller ids, we can consider it as an edgelist, in which the buyers and sellers are the nodes.
i want to consider it as an bipartite network including buyers and sellers, but how can i bipartite it into buyers network and sellers network, please?
if i call bipartitie.mapping, it returns False...
Thanks
