kandi X-RAY | REngine Summary

REngine is a Java library typically used in Artificial Intelligence, Machine Learning applications. REngine has no bugs, it has no vulnerabilities, it has build file available and it has low support. However REngine has a Non-SPDX License. You can download it from GitHub, Maven.
REngine is a general Java interface to R supporting multiple back-ends such as JRI and Rserve. It allows Java code to evaluate R expressions, push and pull data. Since it is backend-agnostic, the same code can be used to embed R into a Java process or use a cluster of R servers to perform statisical computations. The sources can be compiled simply by using. Maven is also supported (including unit tests) and can be run using make mvn.pkg. If you want to run mvn by hamd you can do so, but note that the Maven project requires a different directory structure which can be created by calling mkmvn.sh (unix only as it uses symlinks).

                      QUESTION

                      Loading rdotnet in C# console application fails with an unknown error on macOS

                      Asked 2022-Mar-16 at 17:20

                      I have a very basic C# console application on macOS with the code pasted below. When I try to run this code, the call to REngine.GetInstance() fails with the following exception:

                      Unhandled exception. System.ArgumentException: This 64-bit process failed to load the library libR.dylib. No further error message from the dynamic library loader
                         at DynamicInterop.UnmanagedDll.ThrowFailedLibraryLoad(String dllFullName, String nativeError)

                         at RDotNet.REngine..ctor(String id, String dll)
                         at RDotNet.REngine.CreateInstance(String id, String dll)
                         at RDotNet.REngine.GetInstance(String dll, Boolean initialize, StartupParameter parameter, ICharacterDevice device)
                         at RTest.Program.Main(String[] args) in /Users/.../Projects/RTest/RTest/Program.cs:line 14
                      

                      I have made sure that there are no multiple R installations on the system. Also, tried to execute the same code on the M1 machine as well as on Intel-based Mac.

                      Here is the code:

                      using System;
                      using RDotNet;
                      
                      namespace RTest
                      {
                          class Program
                          {
                              static void Main(string[] args)
                              {
                                  var e = REngine.GetInstance();
                                  e.Initialize();
                      
                              }
                          }
                      }
                      

                      I have also tried explicitly specifying R_HOME and R_PATH using REngine.SetEnvironmentVariables(rPath: "/usr/local/Cellar/r/4.1.2_1/lib/R/lib", rHome: "/usr/local/Cellar/r/4.1.2_1"); but to no avail.

                      Any help will be highly appreciated.

                      Thanks

                      Have you verified that you have two environment variables set. Either via terminal or via your IDE Environment variable setting mechanism?

                      From memory the two you need are:

                      export LD_LIBRARY_PATH=/Library/Frameworks/R.framework/Libraries/:$LD_LIBRARY_PATH
                      

                      and

                      export PATH=/Library/Frameworks/R.framework/Libraries/:$PATH

                      Install REngine

                      You can download it from GitHub, Maven.
                      You can use REngine like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the REngine component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
