get_node_list

Retrieves the node list by selecting and ordering the column <code>node</code> of the
output of the function <code>create_node_labels()</code>.

Provides functions to work with directed (asymmetric) and
undirected (symmetric) spatial networks. It makes the creation of
connectivity matrices easier, i.e. a binary matrix of dimension n x n, where
n is the number of nodes (sampling units) indicating the presence (1) or
the absence (0) of an edge (link) between pairs of nodes. Different network
objects can be produced by 'chessboard': node list, neighbor list, edge
list, connectivity matrix. It can also produce objects that will be used
later in Moran's Eigenvector Maps (Dray et al. (2006) <doi:10.1016/j.ecolmodel.2006.02.015>)
and Asymetric Eigenvector Maps (Blanchet et al. (2008) <doi:10.1016/j.ecolmodel.2008.04.001>),
methods available in the package 'adespatial' (Dray et al. (2023)
