Description

returns the weighted adjacency matrix in dense format

Usage

as_adj_weighted(g, attr = NULL)

Arguments

g

An igraph object

attr

Either NULL or a character string giving an edge attribute name. If NULL a traditional adjacency matrix is returned. If not NULL then the values of the given edge attribute are included in the adjacency matrix.

This method is faster than as_adj from igraph if you need the weighted adjacency matrix in dense format

Value

Numeric matrix
