prepanel.default 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.
