Is a country in a group?

A vectorised membership predicate built on country_groups().

Usage

in_group(x, group, origin = "country.name")

Arguments

x

A vector of country names or codes.

group

A single group name (see country_groups()).

origin

How to read x (default "country.name").

Value

A logical vector the same length as x. A value origin cannot resolve to an ISO code answers FALSE – the same as a country that is genuinely outside the group – so run check_country_match() first if you need to tell "not a member" from "not recognised".

Examples

in_group(c("France", "United States", "Japan"), "EU")
#> [1]  TRUE FALSE FALSE
