hgrid

 the number of smoothing parameters in the grid 

 the base of the logarithm, used in the logarithmic spacing,
   if NULL, then the equal spacing is applied  

base


Returns a grid of smoothing parameter values for kernel estimates,
either with a logarithmic spacing, or with equal spacing,
in decreasing order.


 smooth


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.
