Hi R users
Thanks in advance
Is lifting wavelet transform implemented in R? If so, which package or codes
can be used for performing that?

( I'm top posting for clarity, hotmail decided not to ">" original text and I'm not going to even try to outguess it LOL) I have a non-definitive negative answer : I found two packages but it isn't obvious either expose anything related to lifting. I haven't worked with these lately and so not sure I missed obvious synonyms etc. http://cran.r-project.org/web/packages/wavelets/index.html http://cran.r-project.org/web/packages/waveslim/index.html and normally I would have documentation available for grepping for various terms but quick scan of pdf didn't show anything related to lifting. AFAIK, the wavelet designs are limited to fixed types/lengths and there is no explicit method for deriving new ones and the WT impl is not obvious on a quick read but looks like filters just take coefs and time series and output mra. http://en.wikipedia.org/wiki/Lifting_scheme The Daubechies Sweldens paper seems to be available online etc. ---------------------------------------- Date: Wed, 24 Nov 2010 20:46:30 -0800 From: assaedi76 at yahoo.com To: r-help at r-project.org Subject: [R] Lifting Wavelet Transform Hi R users Thanks in advance Is lifting wavelet transform implemented in R?

Hi:
Package sos is a wonderful tool for this sort of question...
library(sos)
findFn('lifting wavelet transform')
It returned nine possible matches in two packages, adlift and nlt.
HTH,
