[igraph] quick way to load bipartite graphs

[Simone Gabbriellini]

Dear List,

I have a bunch of files where info about bipartite networks are coded this way:

"topic","user","weight"
696,2,1
696,9,2
696,17,1
696,137,1
698,9,3
698,17,3
717,3,1
717,5,1
717,8,1
717,9,8


is there any straightforward way to load one of this files and create
a bipartite network with edge weights? Consider that there could be an
overlap between numbers in the first and second column.
Right now, I only have this code:

net<-as.matrix(read.csv("my file"))
g<-graph.edgelist(net[,-3])

Any help much appreciated.

Best,
Simone
