This new major version of rredlist tracks the development of the IUCN Red List API. The API has been upgraded to v4 and this R package has been updated accordingly. Note that nearly all functionality of the package has changed:
- Most functionality now revolves around retrieving individual or lists of assessments rather than species
- Functions have been added, removed, and renamed accordingly; all existing endpoints of the new API are covered
- The structure of the returned data for most functions has changed, reflecting the change in the structure of the API
Users will need to generate a new API key to use the new version of the API (see rl_use_iucn()).
This package no longer supports v3 of the IUCN Red List API. Older versions of the package may be installed if the old version of the API is needed.
Other major changes and additions
- Switched from performing a single GET call to retrying the GET call if it is rejected or takes too long
- Several old functions that are no longer supported by the new API have been deprecated and may be removed in a future release of rredlist
- Improved the user friendliness of rl_use_iucn()
- Improved type checking of arguments for all functions

- Improved error status code handling and reduced overall query download overhead
- rl_citation() now returns a bibentry and prints a BibTeX entry
- Added IUCN color palette scales for ggplot2
- Added a new vignette demonstrating the use of rredlist within various research pipelines
