In redlist: Interface to the IUCN Red List Data

IUCN Red List stress categories

Description

Retrieve species assessments based on stress categories affecting species. If code = NULL, it returns a list of available stress categories. If code is provided, it retrieves assessments for species affected by the specified stress(es).

Usage

rl_stresses(
  code = NULL,
  year_published = NULL,
  latest = NULL,
  possibly_extinct = NULL,
  possibly_extinct_in_the_wild = NULL,
  scope_code = NULL,
  page = 1
)

Arguments

code	Character or Numeric. One or more stress codes (e.g., "1", "2_1"). Use rl_stresses() to list available stress 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) containing stress categories or species assessments. If code = NULL, the tibble contains available stress categories with columns such as code and description. If code is provided, the tibble contains assessment data for the specified stress(es), including year, taxon details, and other relevant metadata.

Examples

## Not run: 
# List all stress categories
rl_stresses()

# Get species affected by ecosystem stresses (code 1)
rl_stresses(code = "1") # or code = 1

# Get species affected by competition stresses published since 2020
rl_stresses(
  code = "2_3_2",
  year_published = 2020:2023
)

## End(Not run)
