strip.default: Default Trellis strip function

Description

function that draws the strips in trellis functions.

Usage

strip.default(which.given,
              which.panel,
              var.name,
              factor.levels,
              shingle.intervals,
              strip.names = c(FALSE, TRUE),
              style = 1,
              bg = trellis.par.get("strip.background")$col[which.given],
              fg = trellis.par.get("strip.shingle")$col[which.given],
              par.strip.text = trellis.par.get("add.text"))

Arguments

which.given
integer index specifying which of the conditioning variables this strip corresponds to.
which.panel
vector of integers as long as the number of conditioning variables. The contents are indices specifing the current levels of each of the conditioning variables (thus, this would be unique for each distinct panel).
var.name
vector of character strings as long as the number of conditioning variables. The contents are the names of the conditioning variables, to be used if the appropriate entry in strip.names (see below) is true.
factor.levels
if the current strip corresponds to a factor, this should be a character vector giving the levels of the factor (of the form that would be produced by levels(factor)). Otherwise, it should be NULL
shingle.intervals
if the current strip corresponds to a shingle, this should be a 2-column matrix giving the levels of the shingle. (of the form that would be produced by printing levels(shingle)). Otherwise, it should be NULL
strip.names
a logical vector of length 2, indicating whether or not the name of the conditioning variable that corresponds to the strip being drawn is to be written on the strip. The two components give the values for factors and shingles respectively.

style
integer, with values 1,2,3,4,5 and 6 currently supported. Applicable only when x is a factor. Determines how the current level of x is indicated on the strip.

The best way to find out what effect the value of s

par.strip.text
list with parameters controlling the text on each strip, with components col, cex, font
bg
strip background color.
fg
strip foreground color.

Details

default strip function for trellis functions. Useful mostly because of the style argument --- non-default styles are often more informative, especially when the names of the levels of the factor x are small. Typical use is as strip = function(...) strip.default(style=2,...)
