Adjacency matrix of a graph
Transforms the “edge matrix” of a graph into the adjacency matrix.
adjMatrix(A)
A |
a square matrix representing the edge matrix of a graph. |
Given the edge matrix A of a graph, this can be transformed into an adjacency matrix E with the formula E = (A-I)^T.
E |
the adjacency matrix of the graph. |

amat <- DAG(y ~ x+z, z~u+v) E <- edgematrix(amat) adjMatrix(E)
