[igraph] weight in two-mode to one-mode conversion

[Simone Gabbriellini]

Hello List,

I would like to store the number of affiliations each dyads share in a two-mode 
networks.

I am wondering if there's a way, converting from the two-mode to the one-mode 
using bipartite.projection(), to add a weight parameter to the links in the 
one-mode that account for this. 

I am using  the R interface.

thanks in advance and regards,
Simone
