I have matrices with some inter-organizational relations, and with calculated matrices for homophily hypotheses through the bipartite.projection function.
But now I need a matrix that contains links from all nodes to those that have a specific attribute, say "A". For example:
nodes attributes
1 A
2 A
3 B
4 B
5 B
Therefore, the resulting adjacency matrix will be: 1 2 3 4 5
1 0 1 1 1 1
2 1 0 1 1 1
3 1 1 0 0 0
4 1 1 0 0 0
5 1 1 0 0 0
I assume the sample_pa function will not work since the network is based on vertex attributes and
the model should not be random.
How can I get it in Igraph (or other)?Thanks
