  point = NULL,
  no_of_stations = 10,
  ...
)

point	a vector of two coordinates (longitude, latitude) for a point we want to find nearest stations to (e.g. c(80, 6))
no_of_stations	how many nearest stations will be returned from the given geographical coordinates
...	extra arguments to be provided to the graphics::plot() function (only if add_map = TRUE)
