Overview

About

Maintained by Hongyuan JiaFirst published 2026-07-154 releasesCRAN page ↗GitHub ↗

Provides a cross-platform framework for dynamic binding of C libraries using a flexible Foreign Function Interface (FFI). The FFI supports almost all fundamental C types, multiple calling conventions, symbolic access to foreign C struct/union data types and wrapping of R functions as C callback function pointers. Dynamic bindings to shared C libraries are data-driven by cross-platform binding specifications using a compact plain text format; the package includes a 'DynPort' binding specification for 'SDL3' generated from current headers with 'porter'. The package includes a variety of technology demos and OS-specific notes for installation of shared libraries. For the underlying methods and bundled 'DynCall' libraries, see Adler (2012) doi:10.32614/RJ-2012-004 and Adler and Philipp (2008) https://dyncall.org.

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("rdyncall", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

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

Development version from hongyuanjia/rdyncall. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-rdyncall

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-rdyncall

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-rdyncall

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed).
