Project Description: R.NET enables .NET Framework to collaborate with R statistical computing. R.NET requires .NET Framework 4 and native DLLs installed with R environment. You need no other extra installations. Enjoy statistics and programming in your special language with R.
Some examples are below.
Learn how to use R.NET.
Current Issues
- Current version of R.NET is not able to draw charts on the default window device on Windows natively (but see How to display an R Graph in a .NET Winform). Graphics engine is under development.
- Multiple initialization fails (in multiple engines running at the same time ): this problem occurs because native R cannot make multiple initialization in single process. Creating a child process and making an REngine instance in the process is an evasive solution.
Examples
- This example illustrates how R.NET works with C#. More examples are available at Examples page.
Program.cs
using System;
using System.Linq;
using RDotNet;
class Program
{
static void Main(string[] args)
{
// Set the folder in which R.dll locates.
REngine.SetDllDirectory(@"C:\Program Files\R\R-2.12.0\bin\i386");
using (REngine engine = REngine.CreateInstance("RDotNet", new[] { "-q" })) // quiet mode
{
// .NET Framework array to R vector.
NumericVector group1 = engine.CreateNumericVector(new double[] { 30.02, 29.99, 30.11, 29.97, 30.01, 29.99 });
engine.SetSymbol("group1", group1);
// Direct parsing from R script.
NumericVector group2 = engine.EagerEvaluate("group2 <- c(29.89, 29.93, 29.72, 29.98, 30.02, 29.98)").AsNumeric();
// Test difference of mean and get the P-value.
GenericVector testResult = engine.EagerEvaluate("t.test(group1, group2)").AsList();
double p = testResult["p.value"].AsNumeric().First();
Console.WriteLine("Group1: [{0}]", string.Join(", ", group1));
Console.WriteLine("Group2: [{0}]", string.Join(", ", group2));
Console.WriteLine("P-value = {0:0.000}", p);
}
}
}
