drawwp.default {wavethresh} | R Documentation

## Subsidiary routine that actually computes wavelet packet values

### Description

Function computes the values of a given wavelet packet on a discrete grid.

### Usage

    drawwp.default(level, index, filter.number = 10, family = "DaubLeAsymm",
        resolution = 64 * 2^level)

### Arguments

`level` | The resolution level of the packet you want
`index` | The packet index of the packet you want
`filter.number` | The type of wavelet you want, see `filter.select`
`family` | The family of wavelet you want, see `filter.select`
`resolution` | The number of ordinates at which you want the wavelet packet

### Details

Function works by computing a wavelet packet transform of a zero vector. Then inserting a single one somewhere in the desired packet, and then inverts the transform.

### Value

A vector containing the "y" values of the required wavelet packet.
