Accessing the Common Language Runtime (.NET or Mono) from the R statistical software, in-process.
As of May 2019, on Windows Clr requires the .NET Framework (4.6.1+, 4.7.2+ recommended). Groundwork towards running on .NET Core started but it is unclear how to embed the .NET Core runtime into R.
Releases can be found via the release tab of the rClr GitHub repository.
You can install pre-compiled rClr for Windows 10 x64, Ubuntu 18, and CentOS 7 via the release tab of the rClr GitHub repository. Binary packages are available for R 3.6 and 4.x.
Compiling of the master branch from source has been tested under Windows 10 and Linux Ubuntu 18.
On Windows you will need a C# and C and/or Visual C++ compiler. The current releases have been made using the Visual Studio 2019 toolchain. Check the visual studio download page for options.
It is recommended to build the packages in RStudio.
Following path variables must be present in your environment (see How to set an environment variable in Windows 10)
MSBUILD_EXE_PATHpointing to MSBuild.exe, e.g.C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\MSBuild\Current\Bin\MSBuild.exeVSCOMMONpointing to the folder where Visual Studio common folder is located, e.g.C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7. Alternatively, you can set the path in the file `configure.win'.
Install on Ubuntu 18.04. Mono is supported up to versiono 5.18, so make sure that mono 6 is not installed.
