Oggetto: [R] 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", "0")) :
invalid 'row.names' length
My data vector is as follows:

I convert it into a time series and then I get the CWT coefficients. Then I build the tree
that exhibits only 3 branches (see attached plot)
aats <- ts (aa, deltat =1/30, start = 0.0)
aa.cwt <- wavCWT(aats)
aa.tree <- wavCWTTree (aa.cwt)
I can get the data for each of the 3 branches:
> aa.tree[[1]]
