plot.extrpi0: Plotting the Estimated Regression Surface

Description

This function plots the regression surface, overlaid with 3D scatter plot, for objects of class extrpi0, typically resulting from calling the function extrp.pi0.

Usage

## S3 method for class 'extrpi0':
plot(x,y,rgl=TRUE,...)

Arguments

x

the extrpi0 object.

y

the same as rgl. If not missing, it overrides rgl.

rgl

logical, specifying whether or not the rgl package is used for making better 3D interactive graphs.

...

other arguments to be passed to either persp3d, or persp if rgl is not available.

Value

• an invisible(NULL). Used for side effects only.
