In redlist: Interface to the IUCN Red List Data

IUCN Red List assessment scopes

Description

Retrieve species assessments based on their geographic assessment scopes. If code = NULL, it returns a list of available assessment scopes. If code is provided, it retrieves assessments for the specified scope(s).

Usage

rl_scopes(
  code = NULL,
  year_published = NULL,
  latest = NULL,
  possibly_extinct = NULL,
  possibly_extinct_in_the_wild = NULL,
  scope_code = scope_code %||% NA,
  page = 1
)

Arguments

code	Character or Numeric. One or more scope codes (e.g., "1", "2"). Use rl_scopes() to list available scope categories.
year_published	Optional. Single or numeric vector of years to filter assessments by publication year.
latest	Optional. Logical. If TRUE, return only the latest assessment per species.
possibly_extinct	Optional. Logical. Filter for species flagged as possibly extinct.
possibly_extinct_in_the_wild	Optional. Logical. Filter for species possibly extinct in the wild.
scope_code	Optional. Integer One or more scope codes to filter assessments.
page	Optional. Integer vector. Specify one or more page numbers to fetch. If NULL or NA, all pages will be fetched automatically.

Value

A tibble (class tbl_df, tbl, data.frame) where each column represents a unique API response JSON key. If code = NULL, the tibble contains available assessment scopes with columns such as code and description. If code is provided, the tibble contains assessment data for the specified scope(s), including, description, year, latest, taxon details, and other relevant metadata.

Examples

# Get Pan-Africa species assessed species published since 2020
rl_scopes(
  code = "2",
  year_published = 2020:2023
)
