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:

VALUE:

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".
