Lattice panel function for confidence intervals with capped bars

Description

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

Usage

panel.2cat(x, y, subscripts, lower, upper, length = 0.2)

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.
length	Length of the arrow head lines.

  data=Duncan)
e1 <- effect("inc.cat*type", mod)
update(plot(e1), panel=panel.2cat)
