panel.dell: Draw data ellipse

In gmonette/spida2: Collection of tools developed for the Summer Programme in Data Analysis 2000-2012

Draw data ellipse

Description

This is an experiment in writing a function that can be called via layer or glayer without further complications e.g. xyplot(......,labels = rownames(data)) + layer(panel.dell(...)) or xyplot(....., labels = rownames(data), subscripts = T) + glayer(panel.dell(...)).

Usage

panel.dell(x, y, radius = 1, subscripts, type = "l", ...)

Arguments

x, y	points to generate data ellipse
radius	default 1
...	NOTE: may specify anything you don't want passed through ...

Examples

## Not run: 
library(latticeExtra)
xyplot(mathach ~ ses, hs) + layer(panel.dell(..., col='red',lwd=2))
xyplot(mathach ~ ses | school, hs) + layer(panel.dell(...))
xyplot(mathach ~ ses , hs, groups = school) + glayer(panel.dell(...,lwd=2))

## End(Not run)
