About vectorwavelet

The vectorwavelet R package was created for n-dimension wavelet coherence analysis for multivariate time series. Biwavelet R package was used for univariate and bivariate analysis and components.

Besides, multiple wavelet coherence (mwc) in the package is the R transformation of Matlab codes created by Ng, Eric KW, and Chan.

Quadruple (qmwc) and n-dimensional vector wavelet coherence (vwc) are used for multidimensional wavelet analysis with a vectorwavelet package.
