plot.locfit.3d

Plot a high-dimensional "preplot.locfit" object using trellis displays.

Description

This function plots cross-sections of a Locfit model (usually in three or more dimensions) using trellis displays. It is not usually called directly, but is invoked by plot.locfit.

The R libraries lattice and grid provide a partial (at time of writing) implementation of trellis. Currently, this works with one panel variable.

Usage

## S3 method for class 'locfit.3d'
plot(x, main="", pv, tv, type = "level", pred.lab = x$vnames,
               resp.lab=x$yname, crit = 1.96, ...)

Arguments

`x`	`"preplot.locfit"` object.
`main`	title for the plot.
`pv`	Panel variables. These are the variables (either one or two) that are varied within each panel of the display.
`tv`	Trellis variables. These are varied from panel to panel of the display.
`type`	Type of display. When there are two panel variables, the choices are `"contour"`, `"level"` and `"persp"`.
`pred.lab`	label for the predictor variable.
`resp.lab`	label for the response variable.
`crit`	critical value for the confidence level.
`...`	graphical parameters passed to `xyplot` or `contourplot`.
