Browse the group values a grouped enrichment can filter on

Some enrichment doors attach data per group: GRIIS invasive status by country (add_griis()), WCVP native ranges by TDWG region (add_wcvp()), vernacular names by language (add_common_names()), alien first records by country (add_alien_first_records()). This lists the valid group values for such a door, the way enrichment_cols() lists a door's columns, so a country, region, or language code need not be guessed. Read offline from the local .vtr metadata (falling back to the manifest, then a scan of the .vtr); the first call may trigger the one-time download.

Usage

enrichment_groups(source, verbose = TRUE)

Arguments

source

Character. A grouped enrichment name (see list_enrichments()).

verbose

Logical. Print the group column and count. Default TRUE.

Value

A character vector of the available group values, sorted. Stops with a pointer to enrichment_cols() when source is a flat (non-grouped) enrichment, which has no group values.
