_D_e_s_c_r_i_p_t_i_o_n:

     Dynamic three dimensional plot of earthquake hypocentres
     (longitude, latitude and depth) locations.

_U_s_a_g_e:

     threeD(events)

_A_r_g_u_m_e_n_t_s:

  events: defines the events to be plotted. It is an object of class
          '"subset"', generally created by 'subsetcircle',
          'subsetpolygon', 'subsetrect' or 'subsetsphere'.

     This function uses the 'ggobi' R function to display the data and
     provide a dynamical graphics interface. The 'ggobi' function is
     contained in the 'rggobi' package, which is available from CRAN
     (<URL: http://www.r-project.org>). 

     The 'rggobi' package in turn uses the ggobi system software, which
     is external to R. The ggobi system software can be downloaded from
     <URL: http://www.ggobi.org>. Installation instructions are
     included on that site.

     One needs to install the same version of the 'rggobi' package as
     that of the ggobi system software. Older versions of 'rggobi' can
     be found by clicking on "Archive" at the bottom of the contributed
     packages page on CRAN.
