我的代码：
using System;
using System.Linq;
using RDotNet;
namespace ConsoleApplication1
{
class Program
{
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();
}
}
}
报错：
System.IO.DirectoryNotFoundException:“Directory '' does not exist - cannot set the environment variable R_HOME to that value”
显示文件不存在，搜索了半天也没有找到答案，
新手上路，多多指教，十分感谢。
