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.
# S3 method for wp
accessD(wp, level, …)Wavelet packet object
the resolution level that you wish to extract.
any other arguments
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.
