On Linux, the procedure varies by distribution. The setting "RVersion" -> 3 is sufficient regardless of which 3.x version you have installed. Then for Mathematica 9.0.0, 9.0.1 or 10.0.0, use InstallRįor Mathematica 10.0.1, use InstallR If you installed to a non-standard location or are not using the official distribution, then you’ll need to find where these libraries are and modify the path accordingly. If you installed the official R distribution then the path above is correct. This needs to be done every time before running InstallR and specifying an external installation. Note: Users of OS X 10.11 or later must read this first!įirst, we need to make sure that RLink can find the necessary libraries, and set the DYLD_LIBRARY_PATH environment variable, as follows: SetEnvironment I tested the following with the official R distribution from. On OS X, using external R installations is not officially supported, but it does work in practice with any recent version of R. 1 does support R 3.x so if you have Mathematica 10 please use the 10.0.1 update and the latest version of R. Setupīefore setting up RLink to use an external R installation, make sure it works correctly with default settings, then quit the Mathematica kernel. For this reason it is most useful to connect RLink to an external installation of R. Unfortunately by default RLink uses a built-in installation of R (version 2.14, which is quite old) and-except on Windows-it does not allow adding third-party libraries to this installation.
Thus it is essential for RLink to be able to use not only built-in R functions but also arbitrary libraries. R is today the standard computer language for advanced statistics and new computational methods are typically first implemented and published as R libraries. Such functionality is usually contained in third-party R libraries. RLink is primarily useful for accessing functionality that is available in R but not Mathematica. OS X 10.11 El Capitan (and later) users, please see this note. MacOS users with R 3.5 and later, please see this note. This is a guide on how to set up RLink with arbitrary R installations on various operating systems and various versions of Mathematica. RLink is a standard Mathematica package for accessing R functionality from Mathematica.
