Wavelet/Cosine Packet Transform Objects

DESCRIPTION:
Objects of the following classes, the result of transforming a signal to an orthonormal wavelet or cosine packet basis. wpt dwt cpt block.dct

GENERATION:
Objects of classes "wpt", "cpt" are returned from best.basis, best.level, dwt, block.dct or subscripting a ptable object by level.

Objects of class "dwt" are returned from dwt; objects of class "block.dct" are returned from block.dct.


METHODS:
The classes "wpt" and "cpt" have methods for the following generic functions: barplot, boxplot, dotchart, energy.plot, decompose, reconstruct, stack.plot, summary, eda.plot, time.freq.plot.

INHERITANCE:
Both classes "cpt" and "wpt" inherit from class "crystal.vector"; "dwt" inherits from class "wpt", "block.dct" inherits from "cpt".

STRUCTURE:
The "wpt" and "cpt" objects are vectors with the following attributes:
crystal.names:
names of crystals from which the atoms are selected.
lengths:
lengths of the crystals in the basis.
dictionary:
the usual cp.dict or wp.dict object containin all relevent information.
pcosts:
an object of pcosts.
n.levels:
maximum level in the basis.
order:
"depth.first"
