useOuterStrips2: Use outer strips in a lattice display instead of multiple...

In Giza: Constructing panels of population pyramid plots based on lattice

Description

useOuterStrips2 helps to save space in a lattice display by getting rid of the strips above those panels inside the trellis figure while keeping the strips on top of the entire figure. It is a modification of useOuterStrips in the latticeExtra package, but it is able to deal with three factors instead of two.

Used in combination with 'pyramidlattice'.

Usage

useOuterStrips2(x, strip.lines = 1, strip.left.lines = 1)

Arguments

x	An object of class 'trellis'.
strip.lines	height of strips in number of lines.
strip.left.lines	height of left strip in number of lines.

Details

See useOuterStrips in package latticeExtra.

Value

An object of class 'trellis'; essentially the same as 'x', but with strips modified.
