Overview

About

Maintained by Chun Fung Kwok1 releasesCRAN page ↗GitHub ↗

Implements the forward-mode automatic differentiation for multivariate functions using the matrix-calculus notation from Magnus and Neudecker (2019) doi:10.1002/9781119541219. Two key features of the package are: (i) it incorporates various optimisation strategies to improve performance; this includes applying memoisation to cut down object construction time, using sparse matrix representation to speed up derivative calculation, and creating specialised matrix operations to reduce computation time; (ii) it supports differentiating random variates with respect to their parameters, targeting Markov chain Monte Carlo (MCMC) and general simulation-based applications.

Install

R (source archive)pak (dev)openSUSE (OBS)

url <- "https://cran.r-project.org/src/contrib/Archive/ADtools/ADtools_0.5.4.tar.gz"
pkgFile <- "ADtools_0.5.4.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 (0.5.4) 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("kcf-jackson/ADtools")

Development version from kcf-jackson/ADtools. Installs pak first if it is not already available.
