panel.pairs {lattice} | R Documentation |
This is the default superpanel function for splom
.
panel.pairs(z, panel = panel.splom, groups = NULL, panel.subscripts, subscripts, pscales = 5, panel.number, prepanel.limits, ...)
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. |
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).
