          x: The x coordinate of the caveola's position in the
             region.

          y: The y coordinate of the caveola's position in the
             region.

        The `cav' data frame has 138 rows and 2 columns.

        The data gives the positions of the individual caveolae
        in a square region with sides of length 500 units.
        This grid was originally on a 2.65mum square of muscle
        fibre.  The data are those points falling in the lower
        left hand quarter of the region used for the dataset
        `caveolae.dat' in the `spatial' library by B.D. Ripley
        (1994) which is available from Statlib
