similar to: WMTSA "wavCWTPeaks" : Error in if (time.start < times.range[1]) time.start <- times.range[1]

Full_Name: Maura Monville Version: 2.8 OS: Mac OS/X 10.5 Submission from: (NULL) (87.4.122.234) Here is the code that causes wavCWTPeaks error aats <- create.signalSeries(aa, pos=list(from=0.0, by=0.033)) aa.cwt <- wavCWT(aats) x11 (width=10,height=12) plot (aats,main=paste(insig," Cycle: ",j,sep="")) aa.maxtree <- wavCWTTree (aa.cwt,

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 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 ?

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 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",

Dear R family I have a question as to how to get an answer I want to derive with the outcome from R-package, "wmtsa". My concern is that I want to decide equivalent degrees of freedom (EDOF) based on the following outcome. library(wmtsa) W <- wavMODWT(X, wavelet="s8") z1 <- wavEDOF(W) print(z1) #Intentionally, I do not assign n.levels and specify SDF. The following is

I can send data along, but it is too large for the list: I am using wmtsa and the function wavCWT I would like to use the range.scale to only evaluate a subset of frequencies. deltat of the time series that I am trying to analyze is 1 d = wavCWT(RM202.ts, range.scale = c(96, 2688)) and I get the error message Error in wavCWT(RM202.ts, scale.range = c(96, 2688) : Minimum scale must be greater

There is a series of data contains time in fixed step and energy varying with time, how to test its periodicity?In R, it seems there is no direct tools since I have search the R manual with periodic and I have not found any related topic. Thanks a lot

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,

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.

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

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

Hola a todos Estoy tratando de analizaruna serie temporal con datos diarios de temperaturas (40 años). He creado un objeto zoo (con ayuda de la lista, gracias) sobre el que encuentro la regresión lineal. He probado también a crear un objeto ts a partir del zoo. El problema que encuentro es que nose puede aplicar la función stl para hallar la componente estacional y la tendencia. Rdice que la

Hi everybody! I am searching for an R implementation of multi-scale singular spectrum analysis (SSA), which was introduced by Yiou etal (2000) (Data-adaptive wavelets and multi-scale singular-spectrum analysis) and further described in Ghil etal (2002). For SSA alone I found an package recently published on r-forge: http://r-forge.r-project.org/projects/simsalabim/ I am happy about any

Hi, I have little experience using wavelet and I would like to know if it is possible,using R wavelet package, to have a plot of frequency versus time. thank you giov -- View this message in context: http://www.nabble.com/help-on-wavelet-tp19395583p19395583.html Sent from the R help mailing list archive at Nabble.com.

Dear List, R ist somtimes a bit frustrating... I ran the example from http://bm2.genes.nig.ac.jp/RGM2/R_current/library/QRMlib/man/plotMultiTS.html and I get an error. Has someone an explanation for this? Thanks a lot, Steve CODE: library(R.utils) library(tseries) library(wmtsa) library(waveslim) library(brainwaver) library(timeSeries) library(QRMlib) > ?plotMultiTS >

Hi!! I'm looking for a package in R for time series analysis using wavelets( I'm interested on extractingt information from electrocardiograms with the aim of study the heart rate variability) so i want to know which package is the best for me. I've thinking about using some of those(you can recommend me others,xD): *wavelets: A package of funtions for computing wavelet filters,

Hello All, I wanted to perform a fourier transform on high frequency financial data. I have searched and have not found much on this topic for R. I was wondering if anyone has used any libraries for it or have come across any papers I may read. Many Thanks, Neil Gupta [[alternative HTML version deleted]]
