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.

rl_scopes(code = "1")

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