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.

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 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

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

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

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",

There may be some chance that a proper wavelet transform may help me with signal features extraction. I know R contains a number of packages implementing wavelett filters and/or transforms. Is there an implementation of a trous wavelet transform ? Thank you so much, Maura Alice Messenger ;-) chatti anche con gli amici di Windows Live Messenger e tutti i telefonini TIM! Vai su

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 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 <-

In my previous experience with wmtsa function wavCWTPeaks I realized the Tolerance vector passed to the multi-scale decomposition function "wavCWTTree" is crucial for detecting the time series extrema and prevent the R script from aborting. By trial & error I recently managed to figure out the Tolerance vector values in a single case (please see attachments). I am looking for some

I have attached the signal that causes the error message in this email subject. Only columns 1 and 3 have to be considered. It is the work trajectory of a molecule migrating between two equilibrium conformations. The curve has 2 peaks, as shown in its plot. But I keep missing the 2nd one. Here is my short script: library(wmtsa) setwd("C:/Documents and Settings/Monville/Alanine

Hello All. I've installed a new Samba4 server acting like Active Directory Domain Controller. I've joined the domain with a windows 7 and a mac os x workstations. When user password is near to expiration, I'd like that, at login time, it advice that password is near to expiration date. If I user kinit from console it advice me, but it doesn't advice by network login. Is there

Is there a way to write and analysis to disk and then reconstruct the whole thing back into an object. wavCWT() #wmtsa package I am running out of memory on my computer and I was wondering if there was a way to iterate through this process (as it is an iterative process anyway- it just stores the whole thing to memory). Or is there a way to set the scale that I want to look at so that wavCWT

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 am always fascinating by good programming techniques. R contains a lot of very good examples I have been learning from. Since I am using some functions from package "wmtsa", I though I could borrow the elegant example, in the documentation of function "wavBestBasis" to compute the entropy from the Wavelet Transform coefficients. In the following I have pasted the excerpt,
