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

Most Locfit arguments can be passed through |
locfit
, plot.locfit.3d
, 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)
