accessD.wp {wavethresh}R Documentation

Obtain whole resolution level of wavelet packet coefficients from a wavelet packet object (wp).

Description

Get a whole resolution level's worth of coefficients from a wp wavelet packet object. To obtain packets of coefficients from a wavelet packet object you should use the getpacket collection of functions.

Usage

accessD.wp(wp, level, ...)

Arguments

wp Wavelet packet object
level the resolution level that you wish to extract.
... any other arguments

Details

The wavelet packet coefficients are actually stored in a straightforward manner in a matrix component of a wp object so it would not be too difficult to extract whole resolution levels yourself. However, this routine makes it easier to do.

Value

A vector containing the coefficients that you wanted to extract.
