Usage:

xyplot(formula, data, panel=panel.locfit, ...)

Description:

This panel function can be used to add locfit fits to plots generated by trellis.

At the time of writing, it works with xyplot for 1-d fits and crudely with wireframe for 2-d fits.

Arguments:

...

Most Locfit arguments can be passed through xyplot.

Examples:

library("lattice")

# a simple multi-panel display
data(ethanol)
xyplot(NOx~E|C,data=ethanol,panel=panel.locfit)

# The second example uses some Locfit optional arguments.
# Note we can pass the alpha (bandwidth) and family arguments directly to
# xyplot. The cens argument must be given in full; not as a data frame variable.
# The resulting plot does not (yet) distinguish the censored points, but
# the fit will correctly apply censoring.
data(border)
xyplot(runs~day,data=border,panel=panel.locfit,family="poisson",
 alpha=0.3,cens=border$no)
