Webgraph.adjacency creates a graph from an adjacency matrix. The order of the vertices are preserved, i.e. the vertex corresponding to the first row will be vertex 0 in the graph, etc. graph.adjacency operates in two main modes, depending on the weighted argument. If this argument is NULL then an unweighted graph is created and an element of the ...

The adjacency matrix may be used as a data structure for the representation of graphs in computer programs for manipulating graphs. The main alternative data structure, also in use for this application, is the adjacency list. The space needed to represent an adjacency matrix and the time needed to perform operations on them is dependent on the matrix representation chosen for the underlying matrix.
