ergmx.b2nodematch(attr, diff=False, keep=None, alpha=1, beta=1, byb1attr=None, levels=None)

Number of 2-stars centred on first-mode vertices whose two second-mode ends have the same value of attr; the options as in b1nodematch().

Bipartite networks only; b1 terms are about the first mode, b2 terms the second.
