locfit (version 1.5-8)

panel.locfit: Locfit panel function

Description

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

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

Usage

panel.locfit(x, y, subscripts, z, xyz.labs, xyz.axes, xyz.mid, xyz.minmax, 
  xyz.range, col.regions, at, drape, contour, region, groups, ...)

Arguments

...

Most Locfit arguments can be passed through xyplot.

Examples

stopifnot(require(lattice))

# 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)
