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

     Function to calculate a three-dimensional palatographic array
     from.

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

      palate(epgdata) 

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

 epgdata: An eight-columned EPG-compressed trackdata object or an eight
          columned matrix of EPG-compressed trackdata.

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

     An EPG compressed trackdata object that is output from the Reading
     system contains eight columns of data and each row value when
     converted to binary numbers (after adding 1) gives the
     corresponding EPG contact patterns. This function does the
     conversion to binary values.

_V_a_l_u_e:

     An array of three dimensions of 8 rows x 8 columns x n segments
     where n is the number of segments in the trackdata object or
     matrix. The rows and columns are given dimension names, the
     dimension names of the third dimension contains the times at which
     the palatograms occur.

     # convert an EPG-compressed matrix to palatograms
     p <- palate(dcut(coutts.epg, 0, prop=TRUE))
