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.
One of "adjacency"
, "incidence"
, or "edgelist"
