Usage

time_map(
  departure_searches = NULL,
  arrival_searches = NULL,
  unions = NULL,
  intersections = NULL,
  format = NULL
)

Arguments

One or more objects created by make_search

arrival_searches

One or more objects created by make_search

unions

One or more objects created by make_union_intersect

intersections

One or more objects created by make_union_intersect

format

time-map response format. See https://docs.traveltime.com/api/reference/isochrones#Response-Body for details.

Details

Value

API response parsed as a list and as a raw json
