Description: 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)
        <https://CRAN.R-project.org/package=adespatial>). This work is
        part of the FRB-CESAB working group Bridge
