SpletWhen multiple edges are included, multiple=TRUE ,each vertex between \ {i,j\} {i,j } will be counted as many times it appears in the edgelist. So if a vertex \ {i,j\} {i,j } appears 2 times, the adjacency matrix element (i,j) will be 2. Edges with incomplete information (missing data on w or times) are not included on the graph.

SpletIn graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal.
