17 Dec 2014 WaveletComp is an R package for continuous wavelet-based analysis of univariate and bivariate time series. Wavelet functions are implemented in WaveletComp such that a wide range of interme- diate and final results are easily accessible. The null hypothesis that there is no (joint) periodicity in the series

Welcome to the waveslim package. Originally written in S-plus in 1994 and ported to R in 2001, I have taken all the wavelet code I have accumulated over the years and created the waveslim R package. Subroutines to perform wavelet analysis using Hilbert wavelet pairs have also been included by porting Selesnick's
The code in this file makes use of ### just wmtsa and some auxillary R code developed for the workshop. The package ### wmtsa is on cran and can be installed via the following R command: ### ### install.packages("wmtsa") ### ### The packages wavelets and waveslim can be installed in a similar manner using
