defrostR: An Amphibian Systematics Tool

Provides a workflow for combining amphibian taxonomic data sets from different sources that use different taxonomic nomenclature, by suggesting the most current nomenclature used by the Amphibian Species of the World: an Online Reference, Frost (2017) <> for a given input query of species names. It can also be used to extract specific systematic information (e.g. species downstream of a given taxonomic level).
