Description: This resource provides tools to create, compare, and
        post-process spatial isotope assignment models of animal
        origin. It generates probability-of-origin maps for individuals
        based on user-provided tissue and environment isotope values
        (e.g., as generated by IsoMAP, Bowen et al. [2013]
        <doi:10.1111/2041-210X.12147>) using the framework established
        in Bowen et al. (2010)
        <doi:10.1146/annurev-earth-040809-152429>). The package
        'isocat' can then quantitatively compare and cluster these maps
        to group individuals by similar origin. It also includes
        techniques for applying four approaches (cumulative sum, odds
        ratio, quantile only, and quantile simulation) with which users
        can summarize geographic origins and probable distance traveled
        by individuals. Campbell et al. [2020] establishes several of
        the functions included in this package
        <doi:10.1515/ami-2020-0004>.
