plotvolu2d {denpro}R Documentation

Makes a perspective plot of a 2D volume function or a 2D probability content function

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
