Use this if you want to avoid compiling the C++ library, which may be slow and resource-intensive, and ensure that you only use a prebuilt binary. This means you will only get a working arrow R package if a prebuilt binary is found.

LIBARROW_BUILD : If set to false, the build script will not attempt to build the C++ from source.

If no binary is found, installation will fall back to building C++ dependencies from source. See the distro map for compatible binaries and OSs. You may also set it to some other string, a related “distro-version” that has binaries built that work for your OS.

LIBARROW_BINARY : If set to true, the script will try to download a binary C++ library built for your operating system.

See below for more in-depth explanations of these environment variables.

More verbose messaging and regenerates some code Set LIBARROW_BINARY=true and LIBARROW_MINIMAL=false Try to install libarrow binary instead of building from source All boolean variables are case-insensitive. There are a number of other variables that affect the configure script and the bundled build script. If afterwards you install the missing system requirements, you’ll need to reinstall the package in order to enable S3 support. The prebuilt libarrow binaries come with S3 support enabled, so you will need to meet these system requirements in order to use them–the package will not install without them (and will error with a message that explains this).If you’re building everything from source, the install script will check for the presence of these dependencies and turn off S3 support in the build if the prerequisites are not met–installation will succeed but without S3 functionality.

OpenSSL >= 1.0.2: install openssl-devel (rpm) or libssl-dev (deb).

CURL: install libcurl-devel (rpm) or libcurl4-openssl-dev (deb).

gcc >= 4.9 or clang >= 3.3 note that the default compiler on CentOS 7 is gcc 4.8.5, which is not sufficient.

You also need the following system dependencies: To enable it, set the environment variable LIBARROW_MINIMAL=false or NOT_CRAN=true to choose the full-featured build, or more selectively set ARROW_S3=ON.

However, support for working with S3 is not enabled in the default build, and it has additional system requirements. The arrow package allows you to work with data in AWS S3 or in other cloud storage system that emulate S3. Having trouble installing arrow? See the “Troubleshooting” section below. You can also find a more detailed discussion of the code run during the installation process in the developers’ installation docs If you’re contributing to the Arrow project, see vignette("developing", package = "arrow") for resources to help you on set up your development environment. The intended audience for this document is arrow R package users on Linux, and not Arrow developers. This vignette outlines the recommend approaches to installing arrow on Linux, starting from the simplest and least customisable to the most complex but with more flexbility to customise your installation. However, CRAN does not host R package binaries for Linux, and so you must choose from one of the alternative approaches.

If you install arrow from CRAN on a machine running Windows or MacOS, when you call install.packages("arrow"), a precompiled binary containing both the R package and libarrow will be downloaded. This means that when you install arrow, you need both the R and C++ versions. The Apache Arrow project is implemented in multiple languages, and the R package depends on the Arrow C++ library (referred to from here on as libarrow).
