doc |
XML document with Google Maps Distance Matrix API response |
value |
Value to extract, one of: |
A matrix
, where rows represent origins and columns represent destinations. Matrix values are according to selected value
, or NA
if the API returned zero results
The "duration_in_traffic_s"
and "duration_in_traffic_text"
options are only applicable when the API response contains these fields, i.e., when using mp_matrix
with mode="driving"
, with departure_time
specified, and API key key
provided
