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.
