panel.ci: Lattice panel function for confidence intervals

In DAMisc: Dave Armstrong's Miscellaneous Functions

Description

This panel function is defined to plot confidence intervals in a multi-panel lattice display. Note, both lower and upper must be passed directly to xyplot as they will be passed down to the prepanel function.

Usage

	panel.ci(x,y,subscripts, lower,upper,zl)

Arguments

x,y	Data from the call to xyplot.
subscripts	Variable used to created the juxtaposed panels.
lower, upper	95% lower and upper bounds of y.
zl	Logical indicating whether or not a horizontal dotted line at zero is desired.

Examples

library(car)
library(lattice)
data(Ornstein)
mod <- lm(interlocks ~ log(assets)*nation, data=Ornstein)
mod.out <- intQualQuant(mod, c("log(assets)", "nation"), 
	n=25)
xyplot(fit ~ x | contrast, data=mod.out, 
	xlab = "Assets", ylab = "Difference In Fitted Values", 
	lower=mod.out$lower, upper=mod.out$upper, zl=TRUE, 
	prepanel=prepanel.ci, panel=panel.ci)
