Title: Gliding Box Lacunarity and Other Metrics for 2D Random Closed
Sets

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.
