tidygeocoder (version 1.0.5)

reverse_geocode: Reverse geocode coordinates in a dataframe

Description

Takes a dataframe containing coordinates (latitude and longitude) and returns the reverse geocoding query results from a specified service by using the reverse_geo function. See example usage in vignette("tidygeocoder").

This function passes all additional parameters (...) to the reverse_geo function, so you can refer to its documentation for more details on possible arguments.

Usage

reverse_geocode(
  .tbl,
  lat,
  long,
  address = "address",
  return_input = TRUE,
  limit = 1,
  return_coords = NULL,
  unique_only = FALSE,
  ...
)

Arguments

.tbl

dataframe containing coordinates

lat

latitude column name (input data). Can be quoted or unquoted (ie. lat or 'lat').

long

longitude column name (input data). Can be quoted or unquoted (ie. long or 'long').

address

address column name (output data). Can be quoted or unquoted (ie. addr or 'addr').

return_input

if TRUE then the input dataset will be combined with the geocoder query results and returned. If FALSE only the geocoder results will be returned.

limit

maximum number of results to return per input coordinate. For many geocoding services the maximum value of the limit parameter is 100. Pass limit = NULL to use the default limit value of the selected geocoding service. For batch geocoding, limit must be set to 1 (default) if return_coords = TRUE. To use limit > 1 or limit = NULL set return_input to FALSE. Refer to api_parameter_reference for more details.

return_coords

if TRUE return input coordinates. Defaults to TRUE if return_input is FALSE and FALSE if return_input is TRUE. This argument is passed to the reverse_geo() function.

unique_only

if TRUE then only unique results will be returned and return_input will be set to FALSE.

...

arguments passed to the reverse_geo function

Value
