r.net RDotNet.REngine 不包含“GetInstance”的定义

Question

我直接从文档http://jmp75.github.io/rdotnet/tut_basic_types/复制了代码

REngine.SetEnvironmentVariable() 和 REngine.GetInstance() 都会给出编译器错误，指出“RDotNet.REngine”不包含定义。

我安装了 nuget 包 R.Net 版本 1.5.5 并且正在运行 ac# 控制台应用程序。

using System;
using System.Linq;
using RDotNet;

namespace Sample1
{
    class Program
    {
        static void Main(string[] args)
        {
            REngine.SetEnvironmentVariables(); // <-- May be omitted; the next line would call it.
            REngine engine = REngine.GetInstance();
            // A somewhat contrived but customary Hello World:
            CharacterVector charVec = engine.CreateCharacterVector(new[] { "Hello, R world!, .NET speaking" });
            engine.SetSymbol("greetings", charVec);
            engine.Evaluate("str(greetings)"); // print out in the console
            string[] a = engine.Evaluate("'Hi there .NET, from the R engine'").AsCharacter().ToArray();
            Console.WriteLine("R answered: '{0}'", a[0]);
            Console.WriteLine("Press any key to exit the program");
            Console.ReadKey();
            engine.Dispose();

        }
    }
}

我用谷歌搜索，找不到答案。有任何想法吗？

有两个来自不同发行商的 R.Net 块包。我安装错了。哎呀。

此示例的正确包是R.NET.Community。
