我想从C ++代码运行R脚本。 [英] I want to run R script from C++ code.

问题描述

R does not  get compiled into intermediate code. Can any one help on how to integrate R with C++.

我尝试了什么：



尝试运行示例代码以从R脚本调用方法。链接器错误失败。

What I have tried:

Tried running sample code to call a method from R script. Failed with linker errors.

推荐答案

我们可以用C ++代码调用R脚本，如下所示，



#includestdafx.h

#include< iostream>

使用命名空间std;



int main（int argc，char ** argv）{

cout<<Before<< endl;

system（C：\\\\ \\Program Files \\\\\\\\\\\\\\\\\\\\\\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\



返回0;

}



rscript是执行的命令test_script.R。

We can call a R script from C++ code as below,

#include "stdafx.h"
#include <iostream>
using namespace std;

int main(int argc, char **argv) {
cout<<"Before"<<endl;
system("C:\\\"Program Files\"\\R\\R-3.3.2\\bin\\rscript C:\\R-Scripts\\test_script.R");

return 0;
}

rscript is the command that executes the test_script.R.
