lefrig2par: Transforms an evaluation tree so that it can be plotted with...

In delt: Estimation of Multivariate Densities Using Adaptive Partitions

Description

Evaluation trees are trees which are implemented with "left" and "right" pointers. We transform this tree representation to the representation with "parent" pointers (level set tree), so that it can be plotted with the "plottree" function of package "denpro". For example, functions "densplit" and "eval.pick" return evaluation trees.

Usage

lefrig2par(et)

Arguments

et	evaluation tree; result of "densplit", "eval.pick", "eval.cart", ...; see the documentation of "eval.cart"

Value

Returns a level set tree:

parent	parent links
level	height of the node
center	determines the ordering of the nodes
volume	determines the horizontal positioning of the nodes
