Re: [R] Wavelet Package for Time Series

2018-10-13 Thread Jeff Newmiller
Any question about "best" implies an optimization function that will almost certainly vary depending on what you are interested in... please avoid asking such questions. You probably ought to peruse the CRAN time series Task View [1] and try out some options. [1] https://cran.r-project.org/web

Re: [R] Wavelet Package for Time Series

I cannot provide any specific info, but as a matter of policy, packages on CRAN *must* meet their required maintenance standards (compatibility with current R version, run on different OS's, etc.) or they are removed from CRAN. This is not necessarily so for packages on other repos, e.g. github.

[R] Wavelet Package for Time Series

Hi R-help Are there any R users that can tell me which of the wavelet packages are the "best" to use? By this I mean ones that are being maintained, or e.g., work well with ggplot2 or otherwise have specific advantages to use. I have seen for example that WaveThresh has an accompanying book. I

The message is referring to the format of your input data. The package needs a matrix or vector format. I suggest using this: xm<- as.matrix(x) return.modwt<-modwt(xm, filter="la8", n.levels=5, boundary="periodic", fast=TRUE) -- View this message in context: http://r.789695.n4.nabble.com/wav
