  df_points,
  lat = NULL,
  lon = NULL,
  simplify = TRUE,
  curl_proxy = NULL,
  key = get_api_key("roads")
)

Arguments

df_points

data.frame with at least two columns specifying the latitude & longitude coordinates, with a maximum of 100 pairs of coordinates.

lat

string specifying the column of df_path containing the 'latitude' coordinates. If left NULL, a best-guess will be made

lon

string specifying the column of df_path containing the 'longitude' coordinates. If left NULL, a best-guess will be made
