trellis.object: Lattice Display Object

Description

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

Arguments

Value

A ``trellis'' object is a list with the following components:
aspect.filllogical specifying whether aspect==``fill''
aspect.rationumeric, aspect ratio to be used IF aspect.fill is FALSE
as.tablelogical, whether rows are drawn top to bottom
callcall that generated the object. Not used
condlevelsLevels of the conditioning variables
fontsize.normaldefault font size for the plot
fontsize.smallfont size for the axis labels (?)
keylist defining the key to be drawn
layoutlayout 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.
pagethe page function
panelthe panel function
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. If skip=T for a particular panel, then the corresponding element is FALSE instead of a list.
panel.args.commona list containing the arguments common to all the panel functions in name=value form
par.strip.textlist containing graphical parameters cex, col, font for the strip labels
skiplogical vector, not used
stripthe function to draw the strip labels
mainNULL, or list with components label, cex, col, font
subsame as main
xlabsame as sub
ylabsame as xlab
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, same as 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
y.limitssimilar to x.limits
