Return the k nearest geographical neighbours of a language.
nearest_geo_neighbours(id, k, data = WALS)
| id | Language's WALS ID |
|---|---|
| k | How many neighbours to return |
| data | Dataset to consider; by default the entire |
Computed using great_circle_distance.
By default (data = WALS), all languages in the WALS
atlas will be considered in the computation of the nearest neighbours.
By supplying a non-default data argument, it is possible to
override this behaviour, e.g. to supply only a subset of the languages.
If the language does not have as many as k neighbours (e.g. because
of a strict filtering by data), the neighbours that are
found are returned with a warning.
