Defines sparse three-dimensional arrays
	     and supports standard operations on them.
	     The package also includes utility functions for
	     matrix calculations that are common in
	     statistics, such as quadratic forms.

Estimation of one-dimensional probability distributions
	     including kernel density estimation, weighted empirical cumulative
	     distribution functions, Kaplan-Meier and reduced-sample estimators
	     for right-censored data, heat kernels, kernel properties,
	     quantiles and integration.

Contains utility functions for the 'spatstat' family of packages
             which may also be useful for other purposes.

Bayesian inference for parametric proportional hazards spatial
    survival models; flexible spatial survival models. See Benjamin M. Taylor, Barry S. Rowlingson (2017) <doi:10.18637/jss.v077.i04>.

Provides a simple progress bar to use for basic and advanced users that suits all those who prefer procedural programming. It is especially useful for integration into markdown files thanks to the progress bar's customisable appearance.

Tools to convert from specific formats to more general forms of 
    spatial data. Using tables to store the actual entities present in spatial
    data provides flexibility, and the functions here deliberately 
    minimize the level of interpretation applied, leaving that for specific 
    applications. Includes support for simple features,  round-trip for 'Spatial' classes and long-form 
    tables, analogous to 'ggplot2::fortify'. There is also a more 'normal form' representation
    that decomposes simple features and their kin to tables of objects, parts, and unique coordinates.

Encapsulates a number of spatially balanced sampling algorithms,
    namely, Balanced Acceptance Sampling (equal, unequal, seed point, panels), Halton frames 
    (for discretizing a continuous resource), Halton Iterative Partitioning (equal probability) 
    and Simple Random Sampling.
