similar to: a trous wavelet transform in R ?

aa <- (structure(list(X.0.85 = c(-1.02, -1.17, -1.29, -1.39, -1.46, -1.5, -1.52, -1.5, -1.46, -1.39, -1.3, -1.19, -1.07, -0.93, -0.79, -0.65, -0.5, -0.36, -0.22, -0.08, 0.05, 0.18, 0.3, 0.41, 0.52, 0.62, 0.72, 0.81, 0.89, 0.98, 1.05, 1.13, 1.19, 1.25, 1.29, 1.31, 1.31, 1.29, 1.24, 1.16, 1.06, 0.93, 0.77, 0.58, 0.38, 0.16, -0.07, -0.31, -0.89, -1.05, -1.19, -1.31, -1.41, -1.47, -1.51, -1.51,

I am looking for some explanations about the usage of the poorely documented R paclkage Rwave. Has anyone ever tried out its functions for Wavelet Analysis ? Thank you so much.

Thank you for your prompt answer. The breathing signal observations are the amplitude values as a function of time and phase. According to our model the hidden states are the different breathing types. Subjects, whose respiratiion process is regular, are likely to breathe, keeping the same cycle pattern/type, for many consecutive cycles. therefore dwelling in the same hidden state. The more

I keep getting the following error when I look for minima in the series: > aa.peak <- wavCWTPeaks (aa.tree) Error in `row.names<-.data.frame`(`*tmp*`, value = c("1", "0")) : invalid 'row.names' length How can I work it around ? Thank you. Regards, Maura Alice Messenger ;-) chatti anche con gli amici di Windows Live Messenger e tutti i telefonini TIM!

Is there any way to handle errors retuened by R functions ... something like the exception handling in C++ ?

I use FireFox as my favourite web browser on my Mac OS/X 10.5 I double-checked that Java and Java scripts are enabled for FireFox. Nevertheless, I cannot use R on-line search help. I called Apple Tech Assistance but they do not support FireFox. We tried to set Saphari as the favourite browser but evidently R does not support it. Does any one knw of a workaround this annoying problem ? Thanks a

The following error occurs every now and then by calling a function of wmTSA package: Error in `row.names<-.data.frame`(`*tmp*`, value = c("1", "0")) : invalid 'row.names' length I would greatly appreciate some guidelines about how to catch such an error upon its occurrence and have it handled by my own routine rather than letting R stop the currently run

Here is another occurrence of wmTSA internal error. My time series is a short breathing cycle (2425-Cyle_9.txt). Since wmtsa functions that extract extrema seem to expect longer series than I have, I tried the folowing two tricks: 1) I prolong the 1-cycle series on both ends through duplicating the first value (on the left end( and the last value on the right end as any ties as the 1-cycle

I cannot understand the following error printed out when I try to get the extrema of my time series. I would appreciate some suggestion as I really cannot interpret the error. I might not be using a proper set of parameters in calling such functions. I am learning by doing ... > aa.peak <- wavCWTPeaks (aa.tree) Error in `row.names<-.data.frame`(`*tmp*`, value = c("1",

Amo le curve femminili, senza avere una particolare predilezione per questo o quel tipo di curva. Per intenderci, il seno mi piace sia che sia piccolo, sia che sia grande. La sensazione al tatto poi ? sempre diversa e foriera di una straordinaria variet? di emozioni. Di quelli piccoli ? bello disegnare il profilo con un dito (solitamente s'inturgidisce subito... mhhh) di quelli grandi mi piace

I am still fighting with this issue. I did the following: I connected to the NAS with a read-only account called kodi. I traversed various folders and I finally opened an image. Everything went fine. Looking at the logs, the get_entry mask file only shows the final folder: smbd_dirptr_get_entry mask=[Anhelina Viber] found Users/luca/Pictures/Canon/Alessandro/Amici/Anhelina Viber fname=Anhelina

I tried to use R version of package I noticed the original MatLab Pckage is much better documented. I had a look at the R demo code "gtm_demo" and found that variable Y is used in advanced of being created: I wrote my own few lines as follows: inDir <- "C:/Documents and Settings/Monville/Alanine Dipeptide/DBP1/DHA" setwd(inDir) T <-

Hello, I am not expert in wavelet. i am working with a discrete dataset in 3D. I applied the D4 wavelet transform to each dimension sequentially. I made some analysis in the transformed space and i detected some interesting vowel. My question is. How is it possible to map a 3d coordinate in the transformed space to the related coordinate in the 3d original dataset? (i think that probably one

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?    assaedi76@yahoo.com   Thanks     [[alternative HTML version deleted]]

Dear list, in short: I would like to calculate the mean frequency of a signal (e.g. time series) using the wavelet transform. with details: I did not find a R function to calculate a mean frequency using one of the cran packages. My searches using R Site Search returned: **(1)waveclock {waveclock} R Documentation Reconstruction of the modal frequencies in a time series using continuous

Hello, I am thinking about plugging in Discrete Wavelet Transform as described in Vorbis I spec: 1.1.2. Classification Vorbis I is a forward-adaptive monolithic transform CODEC based on the Modified Discrete Cosine Transform. The codec is structured to allow addition of a hybrid wavelet filterbank in Vorbis II to offer better transient response and reproduction using a transform better suited to

Hello, I have to make use of the Cohen-Daubechies-Fauraue (CDF) 9/7 wavelet-transform, but have not found these biorthogonal wavlet in the released packages waveslim, wavethresh or wavelets. Is there any package doing this transform? Or can anybody send me the function doing this? I would be very grateful of that. Thanks Annika

Hello, I forgot in my last reply that my DWT implementation can be speed up, for example I'm doing for now: for (;_X1<_E_;_X1++,_RES+=2) //dilatation { _RES[0]=_X1[0]<<3; _RES[1]=(_X1[1]+_X1[0])<<2; } then for (;_X2<_E_;_X2++,_RES+=2) //details { _RES[0]-=(_X2[1]+_X2[0])<<1; _RES[1]+=6*_X2[1]-_X2[2]-_X2[0];
