Vector map data from <https://www.naturalearthdata.com/>. Access functions are provided in the accompanying package 'rnaturalearth'.

A collection of methods for estimating the basic reproduction
    number (R0) of infectious diseases. Features a web application to interface
    with the estimators. Uses the models from:
        Fisman et al. (2013) <DOI:10.1371/journal.pone.0083622>,
        Bettencourt and Ribeiro (2008) <DOI:10.1371/journal.pone.0002185>, and
        White and Pagano (2008) <DOI:10.1002/sim.3136>.
    Includes datasets for Canadian national and provincial COVID-19 case counts
    provided by Berry et al. (2021) <DOI:10.1038/s41597-021-00955-2>.

Image data used as examples in the loon R package.

Use the <https://api.nbp.pl/> API through R. Retrieve
    currency exchange rates and gold prices data published by the
    National Bank of Poland in form of convenient R objects.

Contains functions to retrieve, organize, and visualize weather data from the NCEP/NCAR Reanalysis (<https://psl.noaa.gov/data/gridded/data.ncep.reanalysis.html>) and NCEP/DOE Reanalysis II (<https://psl.noaa.gov/data/gridded/data.ncep.reanalysis2.html>) datasets.  Data are queried via the Internet and may be obtained for a specified spatial and temporal extent or interpolated to a point in space and time.  We also provide functions to visualize these weather data on a map.  There are also functions to simulate flight trajectories according to specified behavior using either NCEP wind data or data specified by the user.

An interface to the Nexus Class Library which allows parsing
    of NEXUS, Newick and other phylogenetic tree file formats. It provides
    elements of the file that can be used to build phylogenetic objects
    such as ape's 'phylo' or phylobase's 'phylo4(d)'. This functionality
    is demonstrated with 'read_newick_phylo()' and 'read_nexus_phylo()'.

Extract the implied risk neutral density from options using various methods.

To incorporate neighbor genotypic identity into genome-wide association studies, the package provides a set of functions for variation partitioning and association mapping. The theoretical background of the method is described in Sato et al. (2021) <doi:10.1038/s41437-020-00401-w>.
