Return Matrix containing travel times between origins and destinations

table2matrix(lat, lng, destlat = NA, destlng = NA, api = 5,
  profile = "driving", protocol = "v1",
  osrmurl = "http://router.project-osrm.org")

Arguments

lat	Numeric vector containing latitude coordinate for each coordinate to calculate travel times. Also accepts dataframe with latitude in the first column and longitude in the second column.
lng	Numeric vector containing longitude coordinate for each coordinate to calculate travel times.
destlat	Numeric vector containing destination latitude coordinate for each coordinate to calculate travel times. Also accepts dataframe with latitude in the first column and longitude in the second column. Default is value of lat.
destlng	Numeric vector containing longitude coordinate for each destination coordinate to calculate travel times. Default is value of lng.
api	An integer value containing the OSRM API version (either 4 or 5). Default is 5.
profile	OSRM profile to use (for API v5), defaults to "driving".
protocol	The protocol to use for the API (for v5), defaults to "v1".
osrmurl	Base URL of the OSRM service
