Lattice Display Object

Description:

     This class of objects is returned by Lattice display functions,
     and is usually plotted by default by its `print' method.

Value:

     A ``trellis'' object is a list with the following components:

aspect.fill: logical specifying whether aspect==``fill''

aspect.ratio: numeric, aspect ratio to be used IF aspect.fill is FALSE

as.table : logical, whether rows are drawn top to bottom

    call: call that generated the object. Not used

condlevels: Levels of the conditioning variables

fontsize.normal: default font size for the plot

fontsize.small: font size for the axis labels (?)

key      : list defining the key to be drawn

layout   : layout of the trellis. Must be of length 3, but first
          element can be 0, in which case the second element is taken
          to be the desired number of panels per page and a `nice'
          layout is calculated based on aspect ratio, screen dimensions
          etc.

page     : the page function

panel    : the panel function

panel.args: 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. If 'skip=T' for a
          particular panel, then the corresponding element is 'FALSE'
          instead of a list.

panel.args.common : a list containing the arguments common to all the
          panel functions in name=value form

par.strip.text : list containing graphical parameters 'cex, col, font'
          for the strip labels

skip     : logical vector, not used

strip    : the function to draw the strip labels

main     : 'NULL', or list with components 'label, cex, col, font'

sub      : same as main

xlab     : same as sub

ylab     : same as xlab

x.scales : list describing x-scale, can consist of several other lists,
          paralleling panel.args, if x-relation is not ``same''

y.scales : list describing y-scale, same as x.scales

x.between: numeric vector of interpanel x-space

y.between: numeric vector of interpanel y-space

x.limits: numeric vector of length 2 or list, giving x-axis limits

y.limits : similar to x.limits
