Is there anyone in charge of package wmtsa ?
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

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

Help with wavCWTPeaks
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",

How to interpret a result based on wmtsa
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.

wmtsa (wavCWT)
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

misleading example or ...
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,

Help optimizing EMD::extrema()
Hi folks, I'm attempting to use the EMD package to analyze some neuroimaging data (timeseries with 64 channels sampled across 1 million time points within each of 20 people). I found that processing a single channel of data using EMD::emd() took about 8 hours. Exploration using Rprof() suggested that most of the compute time was spent in EMD::extrema(). Looking at the code for EMD:extrema(),

How-To capture and handle errors with R
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

Writing intermediate analysis to disk
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

Found some nice knives with great prices and free shipping
Hey, I found some fantastic looking knives with great prices and free shipping. The website is www.liangdianup.com and these LDU Company people have bayonet knives, folders, switchblades, out the front knives, butterfly knives, and a bunch more. The web address for all of the knives is http://www.liangdianup.com/knives_1.htm I like the all black Extrema Ratio bayonet knife the best but I also like

How to avoid a for-loop?
Hi all, as I am trying to move slowly from just "working" to "good" code, I'd like to ask if there's a smarter way than using a for-loop in tasks like the example below. I need to obtain the extrema of the cumulated sum of a detrended time series. The following code is currently used, please have a look at the comments for my questions and remarks: system.time({ X
