panel.pairs: Default Superpanel Function for splom

Description

This is the default superpanel function for splom.

Usage

panel.pairs(z,
            panel = lattice.getOption("panel.splom"),
            lower.panel = panel,
            upper.panel = panel,
            diag.panel = "diag.panel.splom",
            as.matrix = FALSE,
            groups = NULL,
            panel.subscripts,
            subscripts,
            pscales = 5,            prepanel.limits = function(x) if (is.factor(x)) levels(x) else
            extend.limits(range(as.numeric(x), finite = TRUE)),
            varname.col, varname.cex, varname.font,
            varname.fontfamily, varname.fontface,
            axis.text.col, axis.text.cex, axis.text.font,
            axis.text.fontfamily, axis.text.fontface,
            axis.line.col, axis.line.lty, axis.line.lwd,
            axis.line.alpha, axis.line.tck,
            ...)
diag.panel.splom(x = NULL,
                 varname = NULL, limits, at = NULL, lab = NULL,
                 draw = TRUE,
                 varname.col, varname.cex,
                 varname.lineheight, varname.font,
                 varname.fontfamily, varname.fontface,
                 axis.text.col, axis.text.alpha,
                 axis.text.cex, axis.text.font, 
                 axis.text.fontfamily, axis.text.fontface,
                 axis.line.col, axis.line.alpha,
                 axis.line.lty, axis.line.lwd,
                 axis.line.tck,
                 ...)

Arguments

z

The data frame used for the plot.

panel, lower.panel, upper.panel

The panel function used to display each pair of variables. If specified, lower.panel and upper.panel are used for panels below and above the diagonal respectively.

diag.panel

The panel function used for the diagonals. See arguments to diag.panel.splom to know what arguments this function is passed when called.

as.matrix

logical. If TRUE, the layout of the panels will have origin on the top left instead of bottom left (similar to pairs). This is in essence the same functionality as provided by as.table for the panel layou

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 h

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 cal

x

data vector corresponding to that row / column (which will be the same for diagonal panels).

varname

(scalar) character string or expression that is to be written centred within the panel

limits

numeric of length 2, or, vector of characters, specifying the scale for that panel (used to calculate tick locations when missing)

at

locations of tick marks

lab

optional labels for tick marks

draw

logical, specifying whether to draw the tick marks and labels. If FALSE, only variable names are written

varname.col, varname.cex, varname.lineheight, varname.font, varname.fontfamily, varname.fontface

graphical parameters for the variable name in each diagonal panel

axis.text.col, axis.text.cex, axis.text.font, axis.text.fontfamily, axis.text.fontface, axis.line.col, axis.line.lty, axis.line.lwd, axis.text.alpha, axis.line.alpha

graphical parameters for axis tick marks and labels

axis.line.tck

length of tick marks in diagonal panels

...

extra arguments passed on to panel, lower.panel, upper.panel and diag.panel from panel.pairs. Currently ignored by diag.panel.splom.

Details

panel.pairs 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).

Note that the axis labeling does not support date-time classes at present.
