This class of objects is returned by high level lattice display
functions, and is usually plotted by default by its `print' method.
Arguments
Value
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.settings
par.strip.text
strip
skip
xlab
ylab
describe
index.condlist with index for each of the conditioning variables
perm.condpermutation of the order of the conditioning variables
aspect.fill
{
logical, whether aspect is ``fill''
}
aspect.rationumeric, aspect ratio to be used if aspect.fill is
FALSE
call
{ call that generated the object. }
condlevels
{
list with levels of the conditioning variables
}
legend
{
list describing the legend(s) to be drawn
}
panel.argsa 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.
panel.args.commona list containing the arguments common to all the panel functions
in name=value form
x.scaleslist describing x-scale, can consist of several other lists,
paralleling panel.args, if x-relation is not ``same''
y.scaleslist describing y-scale, similar to x.scales
x.betweennumeric vector of interpanel x-space
y.betweennumeric vector of interpanel y-space
x.limitsnumeric vector of length 2 or list, giving x-axis limits
