Description

Interface to Integrated Taxonomic Information (ITIS)

ritis package API

All functions that start with itis_ work with the ITIS Solr API described at https://www.itis.gov/solr_documentation.html, which uses the package solrium, and these functions have you use the solrium function interfaces, so you can pass on parameters to the solrium functions - so the solrium docs are important here.

All other functions work with the ITIS REST API described at https://www.itis.gov/ws_description.html. For these methods, they can grab data in either JSON or XML format. JSON is the default. We parse the JSON to R native format, either data.frame, character string, or list. You can get raw JSON as a character string back, or raw XML as a character string, and then parse yourself with jsonlite or xml2
