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

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.
The following is

package "wmtsa": how to set up the Tolerance vector to detect time series peaks blindly
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

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. Here is my short script:

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

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

Error when running the examples in plotMultiTS / QRMlib
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

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

Warranty on Accuracy, Precision, Legality, ... of R in Research
(These questions may well have been raised.)
What is the implied warranty of using R for research & publications, consulting, etc.?
Alternately, how does one obtain such a warranty?
Your answers will be much appreciated.
Perhaps you can point me to some websites which discussed this subject in the past.
Thanks & regards
