panel.locfit: Locfit panel function

In locfit: Local Regression, Likelihood and Density Estimation

Locfit panel function

Description

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

Currently it works with xyplot for 1-d fits and crudely with wireframe for 2-d fits.

Usage

panel.locfit(x, y, subscripts, z, rot.mat, distance, shade,
                 light.source, xlim, ylim, zlim, xlim.scaled,
                 ylim.scaled, zlim.scaled, region, col, lty, lwd,
                 alpha, col.groups, polynum, drape, at, xlab, ylab,
                 zlab, xlab.default, ylab.default, zlab.default,
                 aspect, panel.aspect, scales.3d, contour, labels,
                 ...)

Arguments

x, y, subscripts, z	usual arguments to a panel function
rot.mat, distance, shade, light.source, xlim, ylim, zlim, xlim.scaled, ylim.scaled, zlim.scaled, region, col, lty, lwd, alpha, col.groups, polynum, drape, at, xlab, ylab, zlab, xlab.default, ylab.default, zlab.default, aspect, panel.aspect, scales.3d, contour, labels	further arguments passed on to underlying plotting functions
...	Most Locfit arguments can be passed through xyplot.

Examples

## Not run: 
# a simple multi-panel display
data(ethanol, package="locfit")
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, package="locfit")
xyplot(runs ~ day, data=border, panel=panel.locfit, family="poisson",
 alpha=0.3, cens=border$no)

## End(Not run)
