Description
Get geocoded coordinates using the Google Maps Geocoding API
Usage
mp_geocode(
addresses,
region = NULL,
postcode = NULL,
bounds = NULL,
key,
quiet = FALSE,
timeout = 10
)
Arguments
addresses |
Addresses to geocode, as |
region |
The region code, specified as a ccTLD ("top-level domain") two-character value (e.g. |
postcode |
Vector of postal codes to filter the address match by (optional); Note that this is a component filter, which means that for each address, Google will search only within the corresponding postal code if non-missing |
bounds |
A preferred bounding box, specified as a numeric vector with four values xmin/ymin/xmax/ymax (in latitude/longitude) representing the coordinates of the southwest and northeast corners, e.g. as returned by function 'sf::st_bbox'. This can be a single vector (in which case it is replicated) or a |
key |
Google APIs key (optional) |
quiet |
Logical; suppress printing geocode request statuses |
timeout |
|
Value
list
of XML documents with Google Maps Geocoding API responses, one item per element in addresses
