wt.filter-class

An S4 object containing wavelet transform filter information.

classes

This package contains functions for computing and plotting
discrete wavelet transforms (DWT) and maximal overlap discrete
wavelet transforms (MODWT), as well as their inverses.
Additionally, it contains functionality for computing and
plotting wavelet transform filters that are used in the above
decompositions as well as multiresolution analyses.
