plotvolu2d

Output of function "shape2d";
   a list containing fields x, y, z; the meaning of the fealds is the same as
   in the function "persp" 

 Viewing angle (left-right); the same parameter as in "persp"  

theta

 Viewing angle (up-down), the same as in "persp" 

typer


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

We provide tools to
(1) visualize multivariate density functions and density estimates
with level set trees,
(2) visualize level sets with shape trees,
(3) visualize multivariate data with tail trees,
(4) visualize scales of multivariate density estimates with
mode graphs and branching maps, and
(5) visualize anisotropic spread with 2D volume functions and
2D probability content functions.
Level set trees visualize mode structure,
shape trees visualize shapes of level sets of unimodal densities,
and tail trees visualize connected data sets.
The kernel estimator is implemented
but the package may  also be applied for visualizing other density estimates.
