[Rsiena-help] Bipartite network analysis in Rsiena

[Ruth M. Ripley]

Dear Matthew,

What version of RSiena are you using? I have checked the code and see that 
I made an alteration to the relevant part in June, version 1.0.11.109, 
r-forge revision 109.

The adjacency matrix should have rows corresponding to the senders 
and columns corresponding to the receivers.

Regards,

Ruth
