_D_e_s_c_r_i_p_t_i_o_n:

     This class of objects is returned by high level lattice functions,
     and is usually plotted by default by its 'print' method.

_D_e_t_a_i_l_s:

     A trellis object, as returned by high level lattice functions like
     'xyplot', is a list with the '"class"' attribute set to
     '"trellis"'.  Many of the components of this list are simply the
     arguments to the high level function that produced the object.
     Among them are: 'as.table', 'layout', 'page', 'panel', 'prepanel',
     'main', 'sub', 'par.strip.text', 'strip', 'skip', 'xlab' 'ylab',
     'par.settings', 'lattice.options' and 'plot.args'.  Some other
     typical components are:


     '_f_o_r_m_u_l_a' the Trellis formula used in the call

     '_i_n_d_e_x._c_o_n_d' list with index for each of the conditioning
          variables

     '_p_e_r_m._c_o_n_d' permutation of the order of the conditioning variables

     '_a_s_p_e_c_t._f_i_l_l' logical, whether 'aspect' is '"fill"'

     '_a_s_p_e_c_t._r_a_t_i_o' numeric, aspect ratio to be used if 'aspect.fill'
          is 'FALSE'

     '_c_a_l_l' call that generated the object. 

     '_c_o_n_d_l_e_v_e_l_s' list with levels of the conditioning variables

     '_l_e_g_e_n_d' list describing the legend(s) to be drawn

     '_p_a_n_e_l._a_r_g_s' a list as long as the number of panels, each element
          being a list itself, containing the arguments in named form
          to be passed to the panel function in that panel.

     '_p_a_n_e_l._a_r_g_s._c_o_m_m_o_n' a list containing the arguments common to all
          the panel functions in 'name=value' form

     '_x._s_c_a_l_e_s' list describing x-scale, can consist of several other
          lists, paralleling panel.args, if x-relation is not '"same"'

     '_y._s_c_a_l_e_s' list describing y-scale, similar to 'x.scales'

     '_x._b_e_t_w_e_e_n' numeric vector of interpanel x-space 

     '_y._b_e_t_w_e_e_n' numeric vector of interpanel y-space 

     '_x._l_i_m_i_t_s' numeric vector of length 2 or list, giving x-axis
          limits

     '_y._l_i_m_i_t_s' similar to 'x.limits' 

     '_p_a_c_k_e_t._s_i_z_e_s' array recording the number of observations in each
          packet
