accessD.wp: 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, \dots)
Arguments
level
the resolution level that you wish to extract.
Value
- A vector containing the coefficients that you wanted to extract.

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.
