A trellis object, as returned by high level lattice functions like
xyplot, is a list with the
"class" attribute set
"trellis". Many of the components of this list are simply
the arguments to the high level function that produced the object.
Among them are:
plot.args. Some other typical components are:
the Trellis formula used in the call
list with index for each of the conditioning variables
permutation of the order of the conditioning variables
numeric, aspect ratio to be used if
call that generated the object.
list with levels of the conditioning variables
list describing the legend(s) to be drawn
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.
a list containing the arguments common to all the panel functions
list describing x-scale, can consist of several other lists,
paralleling panel.args, if x-relation is not
list describing y-scale, similar to
numeric vector of interpanel x-space
numeric vector of interpanel y-space
numeric vector of length 2 or list, giving x-axis limits
array recording the number of observations in each packet
