adj_list_2_matrix {autoharp}R Documentation

Convert adjacency list to a matrix

Description

Converts a list that represents a tree into a binary matrix.

Usage

adj_list_2_matrix(adj_list)

Arguments

adj_list

The adjacency list of the tree.

Details

Remember that the list has to be for a tree, not a general graph. Please see other help pages for more specifications.

This is a low-level function, used within the S4 class TreeHarp. It is not generally meant for use by the user.

It works by filling up the upper diagonal of the matrix before reflecting it.

Value

A symmetric matrix of 1's and 0's, with 1 in entry (i,j) representing an edge between the two vertices.
