trellis.object {lattice}R Documentation

A Trellis Plot Object

Description

This class of objects is returned by high level lattice functions, and is usually plotted by default by its print method.

Details

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.strip.text, strip, skip, xlab ylab, par.settings, lattice.options and plot.args. Some other typical components are:

formula
the Trellis formula used in the call
index.cond
list with index for each of the conditioning variables
perm.cond
permutation of the order of the conditioning variables
aspect.fill
logical, whether aspect is "fill"
aspect.ratio
numeric, 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.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.
panel.args.common
a list containing the arguments common to all the panel functions in name=value form
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, similar to 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
packet.sizes
array recording the number of observations in each packet
