Manage Graphical User Interfaces (GUI) in R. It is independent from
  any particular GUI widgets ('Tk', 'Gtk2', native, ...). It centralizes info
  about GUI elements currently used, and it dispatches GUI calls to the
  particular toolkits in use in function of the context (is R run at the
  terminal, within a 'Tk' application, a HTML page?).

Creates 3D animated, interactive visualizations that can be viewed in a web browser.

A simple HTTP server allows to connect GUI clients to R.

Function for the GUI API to interact with external IDE/code editors.

Provides functionality to fit and simulate from stationary vine 
  copula models for time series, see Nagler et al. (2022) 
  <doi:10.1016/j.jeconom.2021.11.015>.

R-side code to implement an R editor and IDE in Komodo IDE
  with the SciViews-K extension.

In practice, it is difficult to determine the number of decomposition modes, K, for Variational Mode Decomposition (VMD). To overcome this issue, this study offers Spearman Variational Mode Decomposition (SVMD), a method that uses the Spearman correlation coefficient to calculate the ideal mode number. Unlike the Pearson correlation coefficient, which only returns a perfect value when X and Y are linearly connected, the Spearman correlation can be calculated without knowing the probability distributions of X and Y. The Spearman correlation coefficient, also called Spearman's rank correlation coefficient, is a subset of a wider correlation coefficient. As VMD decomposes a signal, the Spearman correlation coefficient between the reconstructed and original sequences rises as the mode number K increases. Once the signal has been fully decomposed, subsequent increases in K cause the correlation to gradually level off. When the correlation reaches a specific level, VMD is said to have adequately decomposed the signal. Numerous experiments revealed that a threshold of 0.997 produces the best denoising effect, so the threshold is set at 0.997. This package has been developed using concept of Yang et al.
