prunemodes

positive integer; the desired number of modes

modenum

exmalim

maxnum


Prunes smallest modes in terms of the excess mass away, from a level set tree
or froma a shape tree.
The tree is interpreted as a 1D function (in the sense of a volume function,
radius function, or a tail probability function).
The pruning may be useful to get cleaner plots,
especially a location plot of a shape tree may suffer from spurious modes.

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.
