Dear R Users, For running wavelet functions using dwt( ), modwt( ), and mra( ), a wavelet filter algorithm is applied. For all these functions, default is "la8" and other possibility is "haar". In related documents, another possibilities like as symlet and coiflet ... are not cited. Besides "la8" and "haar", which wavelet filters can be used? Thank

Is there a wavelet toolbox in R available that can be compared to the Matlab toolbox for wavelets. Does this toolbox offer the possibility to calculated approximations with different wavelets such as Daubechies 2, Daubechies 3, etc, Symmlet 3, Symmlets 5, etc, Coiflets and so on. I have tried to proceed in this way but I was only able to use one sort of wavelets with a pre-fixed order (i.e. pre-fixed vanishing moments). Thank you for help! Vera Hofer

I take the liberty of pasting the on-line documentation for package "wavelets", functions "dwt" and "wt.filter", pertinent to the wavelet/filter choice. While I apologize for my verbose messages with huge attachments, I encourage whoever loads packages to CRAN to take some minutes to reread the attached documentation. Usage dwt(X, filter="la8", n.levels,
