Extract the adjacency matrix from a neighbor_graph object.

Usage

# S3 method for class 'neighbor_graph'
adjacency(x, attr = "weight", ...)

Arguments

x: A neighbor_graph object.
attr: A character string specifying the edge attribute to use for weights (default: "weight").
...: Additional arguments (currently ignored).

Value

A sparse Matrix object representing the adjacency matrix.

Examples

adj_matrix <- Matrix::Matrix(c(0, 1, 1, 0, 1, 0, 1, 0, 0), 
                            nrow = 3, byrow = TRUE, sparse = TRUE)
ng <- neighbor_graph(adj_matrix)
adj <- adjacency(ng)
