accessD.wp {wavethresh}

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

## S3 method for class 'wp'
accessD(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.
