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

     Returns an index of the top n maximum and minimum  values in 2
     columns of a matrix or data.frame.

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

     genes(dudivar,n=5, axes1=1, axes2=2)

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

 dudivar: a 'data frame' or 'matrix' with at least two columns,
          containing the x,y coordinates.

   axes1: the column number for the x-axis~ 

   axes2: the column number for the y-axis~ 

       n: 

     {n is the number of genes to be extracted}

_D_e_t_a_i_l_s:

     Genes returns an index of the "top" variables at the ends of the x
     and y axes.   Genes is not normally called by the user but is
     called by plotgenes()

     If you wish to return a table or list of the top genes at the end
     of an axis, use the function 'topgenes'.

     Thanks to Miss Jess Mar for helping on this function.
