Return the neighbours of a language residing within a disc of a specified radius from that language.
nearest_geo_neighbours_discoidal(id, radius, data = WALS)
| id | Language's WALS ID |
|---|---|
| radius | Radius of disc in km |
| 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.
