Miscellaneous Functions used within Lattice

Description

These functions are used by various Lattice routines.

Usage

Rows(x, which)
extend.limits(lim, length = 1, prop = 0.07) 
lpretty(lim)
.lattice.print.more
cupdate(index, maxim)
do.breaks(endpoints, nint)
ldrop.levels(x, subset)
compute.layout(...)
make.list.from.intervals(x)
construct.scales(...)
construct.3d.scales(...)
limits.and.aspect(...)
trellis.skeleton(...)
prepanel.default.bwplot(...)
prepanel.default.levelplot(x, y, wx, wy, subscripts, ...)
prepanel.default.cloud(distance, xlim, ylim,
        zlim, zoom = 1, rot.mat = rot.mat, 
        aspect = aspect,...)
prepanel.default.densityplot(...)
prepanel.default.histogram(...)
prepanel.default.parallel(...)
prepanel.default.qq(...)
prepanel.default.qqmath(...)
prepanel.default.splom(...)
prepanel.default.tmd(...)
prepanel.default.xyplot(x, y, type, ...)

Arguments

`length`	desired length of the resulting interval, with center given by the center of lim. Used for relation="sliced".
`prop`	Proportion by which to extend limits.
`x,y`	numeric, factor or shingle.
`subset`	indices to keep.
`which`	logical ?
`lim`	length 2 numeric
`index`	current values of levels
`maxim`	max values of levels
`endpoints`	see histogram
`nint`	see histogram
`zoom, rot.mat,aspect`	see panel.cloud
`distance, xlim, ylim, zlim`	see panel.cloud
`wx, wy, subscripts`	see panel.levelplot
`type`	type argument as in `panel.xyplot`
`...`	other arguments

Details

Some of these functions are indigenous, some are counterparts of functions in the S-Plus Trellis Displays library.

lpretty is used instead of pretty (which gives very non-pretty results in some cases, particularly densityplot).

ldrop.levels returns an object of the same class as x, with the redundant factor/shingle levels dropped, if any. Used to avoid empty panels when using the subset argument.

.lattice.print.more is a global logical to handle the more argument in print.trellis.
