Though unwieldy for large matrices, a full adjacency matrix can be useful for debugging and export.

If the graph is “undirected” then recicprocal edges are explicit in the matrix.

1 | ```
adjacencyMatrix(object)
``` |

`object` |
A |

Thus far only implemented for `graphBAM`

objects.

`adjacencyMatrix`

returns an n x n matrix, where n is
the number of nodes in the graph, ordered in the same manner as
seen in the `nodes`

method. All cells in the matrix are `0`

except where edges are found.
