Hi, I want to perform network regresion with QAP procedure (netlm function of sna package). 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 -------- *Sebastián Goinheix*Instituto de Economía - UdelaR Tel: 24001369 (int. 116) *Por favor, evite imprimir este correo.*
