Description Usage Arguments Author(s) Examples

View source: R/DAMisc_functions.R

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

1
	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.
