Dear All, I have been working on building a new version of the Wavethresh package for some time now. Having build a working version on Linux, I am getting the following error when checking on Windows: C:\Rpackages\R\rw2000\bin>Rcmd check wavethresh * checking for working latex ... OK * using log directory 'C:/Rpackages/R/rw2000/bin/wavethresh.Rcheck' * che...

Hello. I am using the 4.2 version of the wavethresh package available from here: http://www.stats.bris.ac.uk/~wavethresh/ trying to follow the book of Nason (http://www.springer.com/978-0-387-75960-9). I am interested in the analysis of several years time series of daily data with wavelets methods. But the functions of this package only accept dat...

Dear all, A new version of wavethresh has just been submitted to CRAN. This is version 4.5 All best wishes, Guy Nason _______________________________________________ R-packages mailing list R-packages at r-project.org https://stat.ethz.ch/mailman/listinfo/r-packages

Dear, I am using WaveTresh for Haar Wavelets. It works all fine exept when I want to adjust the axis on the wavelet coefficient plot: input: wlh_ponds<-wd(input_waves[,1], family="DaubExPhase",filter.number=1) plot: plot(wlh_ponds,scaling="by.level") My problem is twofold= -I want the original x-axis of the data on that plot, not 1/2 of the axis. This would make

...ients then create a fake sequence of the same length as the original and decompose that sequence using wd form wavethersh with the same wavelet family and filter that was used to decompose the data. Then you can replace the wavelet coefficients and the scaling coefficients using putC and putD from wavethresh. This will leave you with a wd object that you can then reconstruct using wr from wavethresh. I hope this works and is still useful to you.

Hi, Whenever I issue this commands (as in the help for the threshold function), # # Do a 1D decomposition # tdecomp <- wd(test.data) # # Threshold it # tdecomp.thresh <- threshold(tdecomp) # # Reconstruct from the thresholded coefficients # trecons <- wr(tdecomp.thresh) # #

Hi list, I've been trying to install the LS2W package in R. It's originally a S+plus package so things don't work out as planned. Has anyone succesfully installed this package in R (2.2.0)? Cheers, Koen

Hi users, When I use the scaling = by.level, appear in the R, values of the scales by level, but I'm viewing the levels 10, 11, 12, 13 and 14. I do like to have a global scale, using the value of Level 14 ". I would like to see everyone on the same scale level of 14. If I leave the scaling = global, it takes the value of level 10. How i do it? Tks Marize Sim??es

Hi all, I am trying to do wavelets and I got an error message saying "The length of data is not a power of 2" Is there a way of handing that? or should the data length be exactly the power of 2? I am using R version 2.9.2 (2009-08-24) The is library(wavethresh). wds <- wd(ds$v,filter.number=1) Thanks

My Windows machine has gone "kaput" and I am trying to see how R might work on my Mac. I am interested in using the contributed packages, especially "waveslim" and "wavethresh". Are all packages available under either Windows, Mac, or Unix? I can't seem to tell from the documentation whether this is so (probably because I am not very computer literate!). Any thoughts?

Hi all, I am dealing with paleoceanographic data and I have a C14 time serie and one other variable. I would like to perform a spectral analysis (fft or wavelet) and plot it. Unfortunately I don't know the exact script to do this. Does anybody could send me an example to perform my spectral analysis ? I Thank you David Changez de tête et de tenue tous les jours si vous le voulez !

Hello, I use wavethresh packages to perform wavelet analysis. In particular, I would like to compare 2 signals (vectors) after a wavelet decomposition. I would like to use cor.test function, but this function acts on the entire vector values. I plan to perform a cor.test on each level of the wavelet decomposition, say...

Hello, Is there package built for R that can do model/prediction on time series data using wavelet? If not, does anyone know what popular software can do that? Thanks much, yan

Hi There, I tried to find a function in {waveslim} or {wavethresh} in order to recunstruct the decomposed signals. As far as I found there is no function in {waveslim} to recunstruct decomposed data. The function wr{wavethresh} recunstructs the results of wd function. Apart from its limitations ( for example the length of vector must be power of 2 ) it apparent...

Dear R-helpers, I need two simple functions, I guess they exist in R, but I am unable to find them. The first function should cyclically rotate elements in a vector. ("guyrot" in the package "wavethresh" should do it, but there's some problem with its loading) The second function should rotate points in 2D by a given angle (about the defined point). Thanks for any advice Ondra Mikula
