panel.transci: Lattice panel function for translucent confidence intervals
In DAMisc: Dave Armstrong's Miscellaneous Functions

Description Usage Arguments Author(s)

This panel function is defined to plot translucent confidence intervals in a single-panel, grouped (i.e., superposed) lattice display. Note, both lower and upper must be passed directly to xyplot as they will be passed down to the panel function.

1	panel.transci(x, y, groups, lower, upper, ca = 0.25, ...)

`x, y`	Data from the call to `xyplot`.
`groups`	Variable used to created the superposed panels.
`lower, upper`	95% lower and upper bounds of `y`.
`ca`	Value of the alpha channel in [0,1]
`...`	Other arguments to be passed down to the plotting functions.
