  mode = c("driving", "walking", "bicycling", "transit"),
  output = c("simple", "all"),
  urlonly = FALSE,
  override_limit = FALSE,
  ext = "com",
  inject = "",
  ...
)

urlonly: return only the url?
override_limit: override the current query count (.google_distance_query_times)
ext: top level domain domain extension (e.g. "com", "co.nz")
inject: character string to add to the url
...: ...

Value

a data frame (output="simple") or all of the geocoded information (output="all")
