_D_e_s_c_r_i_p_t_i_o_n:

     This is the default panel function for 'parallel'.

_U_s_a_g_e:

     panel.parallel(x, y, z, subscripts,
                    groups = NULL,
                    col, lwd, lty, alpha,
                    common.scale = FALSE,
                    lower,
                    upper,
                    ...,
                    horizontal.axis = TRUE)

_A_r_g_u_m_e_n_t_s:

    x, y: dummy variables, ignored. 

       z: The data frame used for the plot.  Each column will be
          coerced to numeric before being plotted, and an error will be
          issued if this fails. 

subscripts: The indices of the rows of 'z' that are to be displyed in
          this panel. 

  groups: An optional grouping variable.  If specified, different
          groups are distinguished by use of different graphical
          parameters (i.e., rows of 'z' in the same group share
          parameters). 

col, lwd, lty, alpha: graphical parameters (defaults to the settings
          for 'superpose.line').  If 'groups' is non-null, these
          parameters used one for each group.  Otherwise, they are
          recycled and used to distinguish between rows of the data
          frame 'z'. 

common.scale: logical, whether a common scale should be used columns of
          'z'. Defaults to 'FALSE', in which case the horizontal range
          for each column is different (as determined by 'lower' and
          'upper'). 

lower, upper: numeric vectors replicated to be as long as the number of
          columns in 'z'.  Determines the lower and upper bounds to be
          used for scaling the corresponding columns of 'z' after
          coercing them to numeric.  Defaults to the minimum and
          maximum of each column. Alternatively, these could be
          functions (to be applied on each column) that return a
          scalar. 

     ...: other arguments (ignored) 

horizontal.axis: logical indicating whether the parallel axes should be
          laid out horizontally ('TRUE') or vertically ('FALSE'). 

_D_e_t_a_i_l_s:

     Produces parallel coordinate plots, which are easier to understand
     from an example than through a verbal description.  See example
     for 'parallel'
