This operator on a bipartite network evaluates the
formula on the undirected, valued network constructed by
projecting it onto its specified mode. Proj1(formula) and
Proj2(formula) are aliases for Project(formula, 1) and
Project(formula, 2), respectively.
# binary: Project(formula, mode)# binary: Proj1(formula)
# binary: Proj2(formula)
a one-sided ergm()-style formula with the terms to be evaluated
the mode onto which to project: 1 or 2
ergmTerm for index of model terms currently visible to the package.
