_D_e_s_c_r_i_p_t_i_o_n:

     A Trellis 'xyplot' of predictions versus the primary covariate is
     generated, with a different panel for each value of the grouping
     factor. Predicted values are joined by lines, with   different
     line types (colors) being used for each level of grouping.
     Original observations are represented by circles.

_U_s_a_g_e:

     ## S3 method for class 'augPred':
     plot(x, key, grid, ...)

_A_r_g_u_m_e_n_t_s:

       x: an object of class 'augPred'.

     key: an optional logical value, or list. If 'TRUE', a legend is
          included at the top of the plot indicating which symbols
          (colors) correspond to which prediction levels. If 'FALSE',
          no legend is included. If given as a list, 'key' is passed
          down as an argument to the 'trellis' function generating the
          plots ('xyplot'). Defaults to 'TRUE'.

    grid: an optional logical value indicating whether a grid should be
          added to plot. Default is 'FALSE'.

     ...: optional arguments passed down to the 'trellis' function
          generating the plots.

_V_a_l_u_e:

     A Trellis plot of predictions versus the primary covariate, with
     panels determined by the grouping factor.
