As incidence matrix

as_incidence_matrix() was renamed to as_biadjacency_matrix() to create a more consistent API.

Usage

as_incidence_matrix(...)

Details

Some authors refer to the bipartite adjacency matrix as the "bipartite incidence matrix". igraph 1.6.0 and later does not use this naming to avoid confusion with the edge-vertex incidence matrix.
