W2CWM2C reloaded: Ten years later[Formula presented]

Abstract

We present an updated version v2.2 of the R package W2CWM2C (a graphical tool for wavelet (cross) correlation and multiple wavelet (cross) correlation analysis) v1.0. W2CWM2C contains a set of R functions that improve the graphical representations of wavelet correlation and cross-correlation for the bivariate and multivariate cases. The four functions contained in W2CWM2C are highly flexible since these functions contain several parameters to personalize the correlation heat maps and the format of these graphics, which can be displayed on the screen or can be saved as PNG, JPG, PDF or EPS. The W2CWM2C package also helps to handle the input data (multivariate time series) easily as a list of N columns and provides a multivariate dataset to exemplify its use. W2CWM2C is used for the first time to analyse multivariate climate time series. © 2023 The Author(s)
