1.4.stackPlot: Stack plots

Description

Stack plot functions for Lattice.

Usage

stackPlot(x, data = NULL, ...)
   #standard panels
   panel.stackPlot(..., process=TRUE, plot=TRUE, 
            loa.settings = FALSE) 
   #data handlers
   ##currently not exported

Arguments

x

For stackPlot only, a formula with the general structure y ~ x or y1 + y2 ~ x | cond, etc. The elements y1, y2, etc are stacked on the y-axis, and plotted against x. Both are required.

data

For stackPlot only, if supplied, the assumed source of the elements of formula x, typically a data.frame.

...

Additional arguments.

loa.settings, plot, process

loaPlot arguments used to manage panelPal activity.

Value

stackPlot returns trellis objects, much like conventional lattice plot functions.

panel.stackPlot is intended for use within a trianglePlot function call.

Details

stackPlot generates a stack plot using the lattice framework.

panel.stackPlot handles the appearance of triangle plot outputs.

References

These function makes extensive use of code developed by others.

## Basic stack plot usage

#stackPlot(lead~dist.m, data=lat.lon.meuse)
#stackPlot(cadmium+copper+lead+zinc~dist.m, data=lat.lon.meuse)

stackPlot(cadmium*40+copper*5+lead+zinc~dist.m, data=lat.lon.meuse)
