May 14, 2015 at 1:38 PM

I get the from this site but not working, im new in R.Net please help me what is my mistake.

i am using MVC.

            // 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();
Error: could not find function "t.test"
Give me the suggestion.
