Description: Functions for estimating the gliding box lacunarity (GBL),
        covariance, and pair-correlation of a random closed set (RACS)
        in 2D from a binary coverage map (e.g. presence-absence land
        cover maps). Contains a number of newly-developed
        covariance-based estimators of GBL (Hingee et al., 2019)
        <doi:10.1007/s13253-019-00351-9> and balanced estimators,
        proposed by Picka (2000) <http://www.jstor.org/stable/1428408>,
        for covariance, centred covariance, and pair-correlation.  Also
        contains methods for estimating contagion-like properties of
        RACS and simulating 2D Boolean models.  Binary coverage maps
        are usually represented as raster images with pixel values of
        TRUE, FALSE or NA, with NA representing unobserved pixels.  A
        demo for extracting such a binary map from a geospatial data
        format is provided.  Binary maps may also be represented using
        polygonal sets as the foreground, however for most computations
        such maps are converted into raster images.  The package is
        based on research conducted during the author's PhD studies.
