which.matrix.type attempts to choose an appropriate matrix expression for a
network object, or (if its argument is a matrix) attempts to determine whether the matrix is of type adjacency, incidence, or edgelist.
a matrix, or an object of class
The heuristics used to determine matrix types are fairly arbitrary, and should be avoided where possible. This function is intended to provide a modestly intelligent fallback option when explicit identification by the user is not possible.
