當我使用C＃代碼運行Rscript時，出現了我在主題中提到的錯誤。實際上，RMySQL軟件包已正確安裝在我的系統（Windows 7 64位）中，我可以直接從Rconsole運行腳本。但是，從C＃代碼調用時，我得到這個錯誤。請幫助我找到相同的解決方案。謝謝R.NET錯誤「錯誤：'arch = i386'沒有安裝'RMySQL'包'」
這是我的C＃代碼
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using RDotNet;
namespace hottopics_new
{
public partial class hottopic : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnSubmit_Click(object sender, EventArgs e)
{
REngine.SetEnvironmentVariables();
REngine engine = REngine.GetInstance();
engine.Initialize();
var hottopic = engine.Evaluate("source('E:/******/******/Rscript/hottopics.R')").AsDataFrame();
var words = hottopic[1].AsCharacter().ToArray();
var freq = hottopic[2].AsCharacter().ToArray();
Console.WriteLine(words);
Console.WriteLine(freq);
engine.Dispose();
}
}
}
```
我收到錯誤在以下地方在上面的代碼中 「變種hottopic = engine.Evaluate（」 源（」 E：/ **/**/R script/hottopics.R'）「）。AsDataFrame（）;」
這是我的[R腳本
