Feature Extraction for Discretely-Sampled Functional Data R package features version 2025.1 CRAN Task View: NumericalMathematics (https://CRAN.R-project.org/view=NumericalMathematics) Discretely-sampled function is first smoothed. Features of the smoothed function are then extracted. Some of the key features include mean value, first and second derivatives, critical points (i.e. local maxima and minima), curvature of cunction at critical points, wiggliness of the function, noise in data, and outliers in data.
