Regression Spline Functions and Classes R package splines2 version 0.5.4 CRAN Task View: NumericalMathematics (https://CRAN.R-project.org/view=NumericalMathematics) Constructs basis functions of B-splines, M-splines, I-splines, convex splines (C-splines), periodic splines, natural cubic splines, generalized Bernstein polynomials, their derivatives, and integrals (except C-splines) by closed-form recursive formulas. It also contains a C++ head-only library integrated with Rcpp. See Wang and Yan (2021) <doi:10.6339/21-JDS1020> for details.
