Functions for the retrieval, manipulation, and visualization
    of 'geospatial' data, with an aim towards producing '3D' landscape
    visualizations in the 'Unity' '3D' rendering engine. Functions are
    also provided for retrieving elevation data and base map tiles from
    the 'USGS' National Map <https://apps.nationalmap.gov/services/>.

Simulation of reconstructed phylogenetic trees under tree-wide time-heterogeneous birth-death processes and estimation of diversification parameters under the same model. Speciation and extinction rates can be any function of time and mass-extinction events at specific times can be provided. Trees can be simulated either conditioned on the number of species, the time of the process, or both. Additionally, the likelihood equations are implemented for convenience and can be used for Maximum Likelihood (ML) estimation and Bayesian inference.

Delaunay and Voronoï tessellations, with emphasis on the
    two-dimensional and the three-dimensional cases (the package provides
    functions to plot the tessellations for these cases). Delaunay
    tessellations are computed in C with the help of the 'Qhull' library
    <http://www.qhull.org/>.

Easy install and load key packages from the 'tesselle' suite
    in a single step. The 'tesselle' suite is a collection of packages for
    research and teaching in archaeology. These packages focus on
    quantitative analysis methods developed for archaeology. The
    'tesselle' packages are designed to work seamlessly together and to
    complement general-purpose and other specialized statistical packages.
    These packages can be used to explore and analyze common data types in
    archaeology: count data, compositional data and chronological data.
