Several web services are available that provide access to elevation
             data. This package provides access to many of those services and 
             returns elevation data either as an 'sf' simple features object 
             from point elevation services or as a 'raster' object from raster 
             elevation services. In future versions, 'elevatr' will drop 
             support for 'raster' and will instead return 'terra' objects. 
             Currently, the package supports access to the Amazon Web Services 
             Terrain Tiles <https://registry.opendata.aws/terrain-tiles/>, 
             the Open Topography Global Datasets 
             API <https://opentopography.org/developers/>, and the USGS 
             Elevation Point Query Service <https://apps.nationalmap.gov/epqs/>.

A method to calculate the distance to the climatic tree line
    for large data sets of coordinates (World Geodetic System 1984) with 
    geographical uncertainty. The default thresholds and the treeline definition
    is based on Paulsen and Körner (2014) <doi:10.1007/s00035-014-0124-0>, users
    are free to decide what climate layers they would like to use.

Provides R access to election results data. Wraps elex (https://github.com/newsdev/elex/), a Python package and command line tool for fetching and parsing Associated Press election results.

Density, distribution function, quantile function
    and random generation for the Kumaraswamy Complementary Weibull
    Geometric (Kw-CWG) lifetime probability distribution proposed
    in Afify, A.Z. et al (2017) <doi:10.1214/16-BJPS322>.

Performs hypothesis testing for general block designs with
    empirical likelihood. The core computational routines are implemented
    using the 'Eigen' 'C++' library and 'RcppEigen' interface, with
    'OpenMP' for parallel computation. Details of the methods are given in
    Kim, MacEachern, and Peruggia (2023)
