Pre-flight country-match report — check_country

A report on what will and will not match before you trust the map: the input, its iso3c, whether it matched, and a suggestion (the closest known country name by string distance) for misses. Surfaced automatically by join_world().

Usage

check_country_match(
  x,
  origin = "country.name",
  custom_match = wdj_overrides(),
  suggest = TRUE
)

Arguments

x: A vector of country names or codes.
origin: How to read x (any countrycode origin scheme).
custom_match: Overrides applied before matching (default wdj_overrides()).
suggest: Whether to compute closest-name suggestions for misses (requires the optional stringdist package; default TRUE).

Value

A tibble with columns input, iso3c, matched, suggestion.
