geocode_combine | R Documentation |
Executes multiple geocoding queries on a dataframe input and combines
the results. To use a character vector input instead, see the geo_combine function.
Queries are executed by the geocode function. See example usage
in vignette("tidygeocoder")
.
Query results are by default labelled to show which query produced each result. Labels are either
placed in a query
column (if return_list = FALSE
) or used as the names of the returned list
(if return_list = TRUE
). By default the method
parameter value of each query is used as a query label.
If the same method
is used in multiple queries then a number is added according
to the order of the queries (ie. osm1
, osm2
, ...). To provide your own custom query labels
use the query_names
parameter.

.tbl |
dataframe containing addresses |
queries |
a list of queries, each provided as a list of parameters. The queries are, executed by the geocode function in the order provided., (ex. |
global_params |
a list of parameters to be used for all queries, (ex. |
return_list |
if TRUE then results from each service will be returned as separate dataframes. If FALSE (default) then all results will be combined into a single dataframe. |
cascade |
if TRUE (default) then only addresses that are not found by a geocoding service will be attempted by subsequent queries. If FALSE then all queries will attempt to geocode all addresses. |
query_names |
optional vector with one label for each query provided
(ex. |
lat |
latitude column name. Can be quoted or unquoted (ie. |
long |
longitude column name. Can be quoted or unquoted (ie. |
