\title{A Trellis Plot Object}
\description{
This class of objects is returned by high level lattice display
functions, and is usually plotted by default by its `print' method.
}
\value{
A trellis object, as returned by high level lattice functions like
\code{\link{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:
\itemize{
\item{\code{as.table}}
\item{\code{layout}}
\item{\code{page}}
\item{\code{panel}}
\item{\code{prepanel}}
\item{\code{main}}
\item{\code{sub}}
\item{\code{par.settings}}
\item{\code{par.strip.text}}
\item{\code{strip}}
\item{\code{skip}}
\item{\code{xlab}}
\item{\code{ylab}}
}
Some other typical components are:
\describe{
\item{\code{index.cond}}{
list with index for each of the conditioning variables
}
\item{\code{perm.cond}}{
permutation of the order of the conditioning variables
}
\item{\code{aspect.fill}} {
logical, whether \code{aspect} is ``fill''
}
\item{\code{aspect.ratio}}{
numeric, aspect ratio to be used if \code{aspect.fill} is
\code{FALSE}
}
\item{\code{call}} { call that generated the object. }
\item{\code{condlevels}} {
list with levels of the conditioning variables
}
\item{\code{legend}} {
list describing the legend(s) to be drawn
}
\item{\code{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.
}
\item{\code{panel.args.common}}{
a list containing the arguments common to all the panel functions
in \code{name=value} form
}
\item{\code{x.scales}}{
list describing x-scale, can consist of several other lists,
paralleling panel.args, if x-relation is not ``same''
}
\item{\code{y.scales}}{
list describing y-scale, similar to \code{x.scales}
}
\item{\code{x.between}}{ numeric vector of interpanel x-space }
\item{\code{y.between}}{ numeric vector of interpanel y-space }
\item{\code{x.limits}}{
numeric vector of length 2 or list, giving x-axis limits
}
\item{\code{y.limits}}{ similar to \code{x.limits} }
%% also present, but not documented:
%% x.num.limit x.used.at xlab.default
%% y.num.limit y.used.at ylab.default
