Return the geohashes adjacent to input geohashes
gh_neighbors(geohashes, self = TRUE)
gh_neighbours(geohashes, self = TRUE)
geohashes |

self |
Should the input also be returned as a list element? Convenient for one-line usage / piping |
North/south-pole adjacent geohashes are missing three of their neighbors; these will be returned as NA_character_
.
list
with character
vector entries in the direction relative to the input geohashes indicated by their name (e.g. value$south
gives all of the southern neighbors of the input geohashes
).
The order is self
(if self = TRUE
), southwest
, south
, southeast
, west
, east
, northwest
, north
, northeast
(reflecting an easterly, then northerly traversal of the neighborhod).
