Overview

About

Maintained by Niels OlsenCRAN page ↗GitHub ↗

Easy-to-use, very fast implementation of various functional bases. Easily used together with other packages. A functional basis is a collection of basis functions [\phi_1, ..., \phi_n] that can represent a smooth function, i.e. $f(t) = \sum c_k \phi_k(t)$. First- and second-order derivatives are also included. These are the mathematically correct ones, no approximations applied. As of version 1.1, this package includes B-splines, Fourier bases and polynomials.

Install

R (source archive)pak (dev)

url <- "https://cran.r-project.org/src/contrib/Archive/fctbases/fctbases_1.1.1.tar.gz"
pkgFile <- "fctbases_1.1.1.tar.gz"
download.file(url, pkgFile)
install.packages(pkgFile, type = "source", repos = NULL)

This package is no longer on CRAN, so install.packages() cannot fetch it by name. This downloads the last archived source (1.1.1) and builds it locally. Install its dependencies first, and note that building from source needs the usual compiler toolchain.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("naolsen/fctbases")

Development version from naolsen/fctbases. Installs pak first if it is not already available.
