我想使用RInside編譯R代碼。但是在使用函數read.csv時出現錯誤。下面的代碼片段給出:編譯RInside代碼時出錯
include "RInside.h"
include <iomanip>
include <iostream>
include <fstream>
include <string>
include <vector>
include <sstream>
using namespace std;
int main(int argc,char*argv[])
{
RInside R(argc,argv);
SEXP ans;
R.parseEvalQ("library(plotrix)");
R.parseEvalQ("fileContents<-read.csv("/home/nibha/manoj/test.csv")");
R.parseEvalQ("nr <-nrow (filecontents)");
R.parseEvalQ("nc <-ncol (filecontents)");
}
我收到錯誤如下:
: In function ‘int main(int, char**)’:
prog3.cpp:14: error: ‘home’ was not declared in this scope
prog3.cpp:14: error: ‘nibha’ was not declared in this scope
prog3.cpp:14: error: ‘manoj’ was not declared in this scope
prog3.cpp:14: error: ‘test’ was not declared in this scope
prog3.cpp:20: error: ‘myfile’ was not declared in this scope
我認爲你在c中沒有背景。如果你在查看控制檯之前,你會意識到「gedit」(文本編輯器)試圖對着色單詞說些什麼。 – 2011-02-18 08:57:28
Rember認爲這不是R代碼的編譯,只是將它嵌入到C++代碼中 - 這不會更快或者類似的東西。 – mbq 2011-02-18 08:58:18
