  "Description": "Provides an R interface to a C implementation of Fast\nIterative Filtering (FIF) for decomposing a univariate signal\ninto intrinsic mode functions (IMFs) and a residual. The\npackage uses Fast Fourier Transform library FFTW, if found.  If\nnot, it provides instructions to install it for your OS.  This\nis recommended, as R's internal fft(), while avoiding external\nFFT dependencies, is two orders of magnitude slower.  See\nvignette 'Installing FFTW for RFIF' for RFIF installation\ninstructions.",
