In denpro: Visualization of Multivariate Functions, Sets, and Data

Description

Plots the output of function "shape2d"; this is a 2D volume function or a 2D probability content function.

Usage

plotvolu2d(vd, theta = NULL, phi = NULL, typer = "flat")

Arguments

vd	Output of function "shape2d"; a list containing fields x, y, z; the meaning of the fealds is the same as in the function "persp"
theta	Viewing angle (left-right); the same parameter as in "persp"
phi	Viewing angle (up-down), the same as in "persp"
typer	"flat" or "dens"; internal

Value

Plots a perspective plot in the graphics window
