Default Prepanel Functions

Description

These prepanel functions are used as fallback defaults in various high level plot functions in Lattice. These are rarely useful to normal users but may be helpful in developing new displays.

Usage


prepanel.default.bwplot(x, y, horizontal, nlevels, origin, stack, ...)
prepanel.default.histogram(x, breaks, equal.widths, type, nint, ...)
prepanel.default.qq(x, y, ...)
prepanel.default.xyplot(x, y, type, subscripts, groups, ...)
prepanel.default.cloud(perspective, distance,
                       xlim, ylim, zlim,
                       screen = list(z = 40, x = -60),
                       R.mat = diag(4),
                       aspect = c(1, 1), panel.aspect = 1,
                       ..., zoom = 0.8)
prepanel.default.levelplot(x, y, subscripts, ...)
prepanel.default.qqmath(x, f.value, distribution, qtype,
                        groups, subscripts, ..., tails.n = 0)
prepanel.default.densityplot(x, darg, groups, weights, subscripts, ...)
prepanel.default.parallel(x, y, z, ..., horizontal.axis)
prepanel.default.splom(z, ...)

Arguments

`x`, `y`	x and y values, numeric or factor
`horizontal`	logical, applicable when one of the variables is to be treated as categorical (factor or shingle).
`horizontal.axis`	logical indicating whether the parallel axes should be laid out horizontally (`TRUE`) or vertically (`FALSE`).
`nlevels`	number of levels of such a categorical variable.
`origin`, `stack`	for barcharts or the `type="h"` plot type
`breaks`, `equal.widths`, `type`, `nint`	details of histogram calculations. `type` has a different meaning in `prepanel.default.xyplot` (see `panel.xyplot`)
`groups`, `subscripts`	See `xyplot`. Whenever appropriate, calculations are done separately for each group and then combined.
`weights`	numeric vector of weights for the density calculations. If this is specified, it is subsetted by `subscripts` to match it to `x`.
`perspective`, `distance`, `xlim`, `ylim`, `zlim`, `screen`, `R.mat`, `aspect`, `panel.aspect`, `zoom`	see `panel.cloud`
`f.value`, `distribution`, `tails.n`	see `panel.qqmath`
`darg`	list of arguments passed to `density`
`z`	see `panel.parallel` and `panel.pairs`
`qtype`	type of `quantile`
`...`	other arguments, usually ignored

Value

A list with components xlim, ylim, dx and dy, and possibly xat and yat, the first two being used to calculate panel axes limits, the last two for banking computations. The form of these components are described in the help page for xyplot.
