Packet Table Objects

DESCRIPTION:
Objects of class "ptable" that result from creating a wavelet or cosine packet table.

GENERATION:
Objects of class "ptable" are returned from cp.table, wp.table, as.ptable or subscripting the first j levels of a ptable object.

METHODS:
The class "ptable" has methods for the following generic functions: $, $<-, [, [<-, [[, [[<-, best.basis, best.level, boxplot, energy.plot, pcosts, plot, print, summary, eda.plot.

as.ptable coerces a cpt or wpt object to a ptable object.


INHERITANCE:
Class "ptable" inherits from class "crystal.vector" or "crystal.list".

STRUCTURE:
The "ptable" object, or packet table, is a long vector, or a list of vectors (when boundary="infinite") with the following attributes:
crystal.names:
names of the crystals in the packet table.
lengths:
lengths of the crystals in the packet table. Exists only when ptable inherits from class crystal.vector, i.e. the ptable object is a long vector.
dictionary:
the usual cp.dict or wp.dict object containing all relevant information.
pcosts:
a pcosts object, containing the cost values of all the crystals in the packet table.
n.levels:
number of levels of the ptable object.
order:
"sequency", "natural" or "depth.first".
