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")
)

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

Arguments

doc

XML document with Google Maps Distance Matrix API response

value

Value to extract, one of: "distance_m" (the default), "distance_text", "duration_s", "duration_text", "duration_in_traffic_s", "duration_in_traffic_text"

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")

if (FALSE) {
# Text file with API key
key = readLines("~/key")

locations = c("Tel-Aviv", "Jerusalem", "Neve Shalom")

# Driving times
doc = mp_matrix(
  origins = locations,
  destinations = locations,
  mode = "driving",
  departure_time = Sys.time() + as.difftime(10, units = "mins"),
  key = key
)
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")
mp_get_matrix(doc, value = "duration_in_traffic_s")
mp_get_matrix(doc, value = "duration_in_traffic_text")

# Public transport times
doc = mp_matrix(
  origins = locations,
  destinations = locations,
  mode = "transit",
  key = key
)
mp_get_matrix(doc, value = "distance_m")
