Use the httr::GET() to send a request to the Google Maps API for geocoding
information. The query will concatenate all the geographical information that
is passed in into a single string. Then the function pulls the
formatted_address endpoint of the API results and extracts the the first
field of the result. Note that you will need to pass in your Google Maps
Place API key with the key argument.
fetch_city(address = NULL, key = NULL)A vector of street addresses. Sent to the API as one string.
A character containing your alphanumeric Google Maps API key.
A character vector of formatted address endpoints from Google. This
will include all the fields from street address, city, state/province,
zipcode/postal code to country/regions. NA_character_ is returned for
all errored API calls.
