[Rsiena-help] Bipartite network analysis in Rsiena

[Ruth M. Ripley]

Dear Matthew,

I do not quite understand your description, but think that you may be 
trying to use a pajek file format with two mode data. This is not 
possible in RSiena: you can use either adjacency matrices or Siena net 
edgelists (the latter are described in the RSiena manual).

On the siena01Gui screen you need to define two names for the nodes in the 
ActorSets column (just leave a space between the two names), and if you 
use a Siena net you need to define the size of the network with 2 integers 
in the NbrOfActors column.

An example session file might look like the attached, assuming you want to 
use a Siena net edgelist rather than an adjacency matrix with your data 
size.

I think the error message is probably due to incorrect data format.

Hope this helps,

Regards,

Ruth
