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

  length: desired length of the resulting interval, with center given
          by the center of lim. Used for relation="sliced". 

    prop: Proportion by which to extend limits.  

     x,y: numeric, factor or shingle. 

  subset: indices to keep. 

   which: logical ?

     lim: length 2 numeric

   index: current values of levels

   maxim: max values of levels

endpoints: see histogram

    nint: see histogram

zoom, rot.mat,aspect: see panel.cloud

distance, xlim, ylim, zlim: see panel.cloud

wx, wy, subscripts: see panel.levelplot

    type: type argument as in `panel.xyplot'

     ...: other arguments

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

     Some of these functions are indigenous, some are counterparts of
     functions in the S-Plus Trellis Displays library.

     `lpretty' is used instead of pretty (which gives very non-pretty
     results in some cases, particularly densityplot).

     `ldrop.levels' returns an object of the same class as `x', with
     the redundant factor/shingle levels dropped, if any. Used to avoid
     empty panels when using the `subset' argument.

     `.lattice.print.more' is a global logical to handle the `more'
     argument in print.trellis.
