Curated country-name overrides (replaces the silent drop-list)

A documented custom_match table for entities that map backends (ggplot2::map_data() and Natural Earth) get wrong or leave without an ISO code. Earlier versions of the package deleted these regions; now they are matched instead, so they stop silently disappearing from maps.

country_overrides() is the preferred name as of the package's rename to countryatlas; wdj_overrides() is kept as a backward-compatible alias.

Usage

wdj_overrides(extra = NULL)

country_overrides(extra = NULL)

Arguments

extra

An optional named character vector of additional overrides (names are country/region names, values are iso3c codes). Merged on top of the built-in table, so you can extend or override it, e.g. wdj_overrides(c(Somaliland = "SOM")).

Value

A named character vector suitable for countrycode(custom_match=).

Details

The table maps a country/region name (as spelled by the geometry backends) to an ISO 3166-1 alpha-3 code. Pass the result as the custom_match argument to standardize_country(), world_data() and friends. Every downstream code (iso2c, continent, region, flag, ...) is derived from this iso3c, so a single override is enough.
