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.list", "wpt" "cpt.list" and "cpt" are returned from best.basis, best.level, dwt, block.dct or subscripting a wp.table, cp.table, cp.table.list or wp.table.list object by level. Objects of class "dwt" and "dwt.list" are returned from dwt; objects of class "block.dct" are returned from block.dct.

METHODS:

The classes "wpt" and "wpt.list" have methods for the following generic functions:

barplot, boxplot, dotchart, energy.plot, decompose, reconstruct, stack.plot, summary, eda.plot, time.freq.plot .

INHERITANCE:

The classes "cpt" and "wpt" inherit from class "crystal.vector"; The classes "cpt.list" and "wpt.list" inherit from class "crystal.list"; "dwt" inherits from class "wpt", "block.dct" inherits from "cpt". "dwt.list" inherits from class "wpt.list", "block.dct" inherits from "cpt".

STRUCTURE:

The "wpt" , "cpt" , "wpt.list" and "cpt.list"objects are vectors with the following attributes:

VALUE:

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"
