Description: 
  The package provides functions to construct level set trees 
  of some multivariate density estimates and density functions.
  With level set trees we may visualize
  the number and location of modes,
  the relative importance of the modes,
  the barycenters of the separated regions of level sets,
  and skewness and kurtosis of the density.
  The visualization methods may be applied in exploratory data analysis,
  to make graphical inference on the existence of the modes,
  and to apply graphical methods to choose the smoothing parameter.
  The package provides also functions to construct shape trees of connected level sets.  
  Visualization with level set trees and shape trees is in many cases more
  effective and easy to use than the method of looking at slices and
  projections of a density function.
  The package implements the kernel estimator
  but the package may be applied for visualizing
  other density estimates, which have to be setwise constant. 
  The package provides also tools to visualize multivariate data;
  it provides parallel tail tree plots and cumulative tail frequency plots.
