Get addresses from locations using the HERE 'Geocoder' API.
The return value is an sf object, containing point geometries
with suggestions for addresses near the provided POIs.
reverse_geocode(poi, results = 1, sf = TRUE, url_only = FALSE)sf object, Points of Interest (POIs) of geometry type POINT.
numeric, maximum number of results (Valid range: 1 and 100).
boolean, return an sf object (default = TRUE) or a
data.frame?
boolean, only return the generated URLs (default = FALSE)?
If sf = TRUE, an sf object, containing the position coordinates
of the reverse geocoded POIs as geometry list column and the access
coordinates as well-known text (WKT).
If sf = FALSE, a data.frame containing the
coordinates of the reverse geocoded POIs as lng, lat columns.
If no addresses are found near a POI, NULL for this POI is returned.
In this case the rows corresponding to this particular POI are missing and merging the POIs by row is not possible.
However, in the returned sf object, the column "id" matches the rows of the input POIs.
The "id" column can be used to join the original POIs.
