rSharp

The rSharp R package provides access to .NET libraries from R. It allows to create .NET objects, access their fields, and call their methods.

This package is based on the rClr package and utilizes some of its code base.

Important notes

As rSharp is provided with precompiled binary files, it is currently a binary package.

The package utilizes two code bases - the R code which is exposed to the user, and the C++/C# code that communicates with the .NET libraries. The end user of the package will only interact with the R code, and pre-build C++/C# libraries are supplied with the package. See section Installation for instructions on how to install the package.

Advanced users and C++/C# developers might want to build the C++/C# code from source. For this, follow the instructions in section Build.

Installation

Windows

Prerequisites

• Latest Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 available here
• .NET 8 runtime available here.

Install from Github

You can install the package from GitHub with pre-build binaries by running:

install.packages("pak")
pak::pak("Open-Systems-Pharmacology/rSharp@*release")

Get the latest development version with:

pak::pak("Open-Systems-Pharmacology/rSharp")

Install from Binary

Alternatively, download the attached binary file from latest release, and install it locally using:

install.packages("path/to/rSharp_X.zip",  type = "win.binary")

Ubuntu

Run the following commands to install the required dependencies:

sudo apt-get install dotnet-runtime-8.0 libcurl4-openssl-dev libssl-dev libxml2-dev 
sudo apt-get install libfontconfig1-dev libharfbuzz-dev libfribidi-dev
sudo apt-get install libfreetype6-dev libpng-dev libtiff5-dev libjpeg-dev

Symlink libdl.so.2 to libdl.so

sudo ln -s /usr/lib/x86_64-linux-gnu/libdl.so.2 /usr/lib/x86_64-linux-gnu/libdl.so

Install the package from GitHub with pre-build binaries by running:

install.packages("remotes")
pak::pak("Open-Systems-Pharmacology/rSharp@*release")

Get the latest development version with:

pak::pak("Open-Systems-Pharmacology/rSharp")

Build

Windows

To build the C++/C# libraries from source, make sure the Desktop development with C++ workload is installed in Visual Studio.

Create an environment variable R_INSTALL_PATH and set the value to the path where R is installed

set R_INSTALL_PATH = "C:\Program Files\R\R-4.3.3"

Start Visual Studio and open the rSharp.sln solution file and build the solution. The build process will automatically copy the required files to the rSharp/inst/lib folder.

Then start your preferred R environment and run the following R commands from within the rSharp folder

devtools::install()

Ubuntu

Set up .NET SDK and nuget (the latter to get the required dependencies)

Optionally set up to build the binaries

sudo apt-get install dotnet-sdk-8.0
sudo apt-get install nuget

Navigate to the rSharp\shared directory and run

make

Then change back to the rSharp directory start your preferred R environment and run the following R commands

devtools::install()

User guide

Examples of interacting with .NET assemblies using this package are detailed in vignette('user-guide'). Some useful tips around using the package are available in the vignette('knowledge-base').

Code of conduct

Everyone interacting in the Open Systems Pharmacology community (codebases, issue trackers, chat rooms, mailing lists etc…) is expected to follow the Open Systems Pharmacology code of conduct.
