在Windows上从C++调用R函数

Question

我想从Windows上的C++调用R函数。我使用MinGW来编译程序，但它在编译时会引发错误。均码（从德克拍摄）和编译错误如下：

#include <iostream> 
using namespace std; 
#include "RInside.h" // for the embedded R via RInside 


Rcpp::NumericMatrix createMatrix(const int n) { 
    Rcpp::NumericMatrix M(n,n); 
    for (int i=0; i<n; i++) { 
    for (int j=0; j<n; j++) { 
     M(i,j) = i*10+j; 
    } 
    } 
    return(M); 
} 

int main(int argc, char *argv[]) { 
    const int mdim = 4;       // let the matrices be 4 by 4 
    SEXP ans; 


    RInside R(argc, argv);      // create an embedded R instance 

    Rcpp::NumericMatrix M = createMatrix(mdim); // create and fill a sample data Matrix 
    R["M"] = M;         // assign C++ matrix M to R's 'M' var 

    std::string evalstr = "\ 
      cat('Running ls()\n'); print(ls());     \ 
      cat('Showing M\n'); print(M);       \ 
      cat('Showing colSums()\n'); Z <- colSums(M); print(Z); \ 
      Z";      // returns Z 

    ans = R.parseEval(evalstr);     // eval the init string -- Z is now in ans 

    Rcpp::NumericVector v(ans);     // convert SEXP ans to a vector of doubles 
    for (int i=0; i< v.size(); i++) {   // show the result 
    std::cout << "In C++ element " << i << " is " << v[i] << std::endl; 
    } 

    return 0; 
} 

编译：

g++ -I "C:\ProgramFiles\R\R-2.14.0\library\RInside\include" -I "C:\Progra 
mFiles\R\R-2.14.0\library\Rcpp\include" -I "C:\ProgramFiles\R\R-2.14.0\include" 
RFunctions.cpp -o sh1.exe 

错误：

任何想法我很想念？

Answer 1

你实际上并没有在R库中进行链接（不管是什么）。

Answer 2

吉姆在他之前的回答中是正确的，但还有更多。

当使用RInside，还需要

1. 包括并用Rcpp链路（其RInside取决于）一个

2. 包括与链路与R（其中两个取决于）以及当然

3. RInside自己的图书馆

这样做的最简单方法是简单地使用examples/standard目录中的Makefile--假定您复制了其中一个示例的代码，您还应该复制构建指令。

最后，这是您最大的问题：RInside应用程序目前不在Windows上工作，这在RInside页面上有明确记录。它会建立，但在启动时发生段错误。调试帮助将不胜感激，这适用于OS X和Linux。
