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

     ...: At least one argument consisting of a points data set must be
          specified. 

    cpch: A vector of characters for plotting symbols 

     add: if 'add' is 'TRUE' then overlay on an existing plot 

    type: plot data as points if 'type="p"', lines if 'type="l"'

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

     'mpoint' enables several point or polygon datasets to be
     overlayed. The plot region is calculated so that all the specified
     datasets fit in the region. The parameter 'cpch' specifies the
     characters to use for each set of points. The default 'cpch'
     consists of the numbers 1 to 9 followed by the uppercase  letters
     A to Z. If 'cpch' is shorter than the number of point sets to
     plot, then it is repeated.
