R语言与.net 集成开发入门

首先：R语言的基本教程：

下载R语言的安装包：https://cran.r-project.org/bin/windows/base/old/3.4.1/

新建：vs工程控制台

添加nuget包：R.net

添加测试代码：

 static void Main(string[] args)

        {

            REngine.SetEnvironmentVariables();

            // There are several options to initialize the engine, but by default the following suffice:

            REngine engine = REngine.GetInstance();

            // .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.Evaluate("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.Evaluate("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);

            // you should always dispose of the REngine properly.

            // After disposing of the engine, you cannot reinitialize nor reuse it

            engine.Dispose();

            Console.ReadKey();

        }

　　运行结果：
