WebIf this argument is NULL then an unweighted graph is created and an element of the adjacency matrix gives the number of edges to create between the two corresponding vertices. The details depend on the value of the mode argument: "directed". The graph will be directed and a matrix element gives the number of edges between two vertices. WebMar 25, 2024 · Since there’s an edge going from node 1 to 2, we see a 1 in both A12 (row 1, column 2) and A21 (row 2, column 1). The lack of directionality in the graph results in a symmetric matrix.
