The package uses Fast Fourier Transform library FFTW, if found. If not, it provides instructions to install it for your OS. This is recommended, as R's internal fft(), while avoiding external FFT dependencies, is two orders of magnitude slower. See vignette 'Installing FFTW for RFIF' for RFIF installation instructions.https://github.com/r-universe/chuckcoleman/actions/runs/26407736871Mon, 25 May 2026 15:18:48 GMTRFIF1.0.2successhttps://chuckcoleman.r-universe.devhttps://github.com/chuckcoleman/rfifinstall-fftw3l.Rmdinstall-fftw3l.htmlInstalling FFTW for RFIF2026-04-10 20:59:212026-04-10 20:59:21rfif.Rmdrfif.htmlRFIF: Fast Iterative Filtering in R2026-03-24 20:46:332026-03-24 20:46:33
