Default Superpanel Function for splom

Description

This is the default superpanel function for splom.

Usage

panel.pairs(z, panel = panel.splom,
            groups = NULL, panel.subscripts, 
            subscripts,
            pscales = 5,
            panel.number,
            prepanel.limits,
            ...)

Arguments

z The data frame used for the plot.
panel The panel function used inside.
groups Grouping variable, if any.
panel.subscripts logical specifying whether the panel function accepts an argument named subscripts.
subscripts The indices of the rows of z that are to be displayed in this (super)panel.
pscales Controls axis labels, passed down from splom. If pscales is a single number, it indicates the approximate number of equally-spaced ticks that should appear on each axis. If pscales is a list, it should have p components, each of which is itself a list with the following valid components:
at: a numeric vector specifying tick locations
labels: character vector labels to go with at
limits: numeric 2-vector specifying axis limits (should be made more flexible at some point to handle factors)
These are specifications on a per-variable basis, and used on all four sides in the diagonal cells used for labelling.
Factor variables are labelled with the factor names. Use pscales=0 to supress the axes entirely.
panel.number the sequential index of the panel in the Lattice plot which this function will draw, meant to keep track of the conditioning variable for the panel. Passed to the `panel' function if it accepts such an argument.
prepanel.limits The `regular' high level lattice plots such as xyplot use the prepanel function for deciding on axis limits from data. This function serves a similar function, and works on a per-variable basis, by calculating the limits, which can be overridden by the corresponding limits component in the pscales list.
... graphical parameters may be supplied.

Details

This is the function that is actually passed in as the panel function in a trellis object produced by splom (taking the `panel' function as its argument).
