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. x in is.characterOrExpression can be an arbitrary S object, in rearrangeUnit, a grid 'unit' vector.

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

pos

integer

u

grid unit object of length 1

at, labels, logpaste, abbreviate, minlength, format

arguments used in calculateAxisComponents

names.current, new.prefix

names to disambiguate and new prefix

...

other arguments

synopsis

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.

rearrangeUnit is a hack that emulates x[pos] <- u

calculateAxisComponents is modified from axis.POSIXct. This aims to be a general function which given a general 'range' x and optional at, generates the locations of tick marks and corresponding labels. Ultimately will be a replacement for lpretty.
