mp_get_matrix {mapsapi} | R Documentation |
Extract distance or duration *matrix* from a Google Maps Distance Matrix API response
Description
Extract distance or duration *matrix* from a Google Maps Distance Matrix API response
Usage
mp_get_matrix(
doc,
value = c("distance_m", "distance_text", "duration_s", "duration_text",
"duration_in_traffic_s", "duration_in_traffic_text")
)
Arguments
doc |
XML document with Google Maps Distance Matrix API response |
value |
Value to extract, one of: |
Value
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
Note
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
Examples
library(xml2)
doc = as_xml_document(response_matrix)
mp_get_matrix(doc, value = "distance_m")
mp_get_matrix(doc, value = "distance_text")
mp_get_matrix(doc, value = "duration_s")
mp_get_matrix(doc, value = "duration_text")
