#include <rcpp11>找不到文件错误</rcpp11>

标签: r rstudio rcpp11

我正在尝试使用来自它的来源的Rcpp11包来源:

devtools::install_github("Rcpp11/Rcpp11")

我在这里阅读:http://blog.r-enthusiasts.com/2014/05/27/disambiguating-rcpp11-and-rcpp/

我可以在include <Rcpp11>文件的头部使用using namespace Rcpp11 + .cpp但我在采购时遇到此错误:

 egfile.cpp:1:10: fatal error: 'Rcpp11' file not found
 #include <Rcpp11>
           ^
 1 error generated.

其中egfile.cpp

#include <Rcpp11>
using namespace Rcpp11;

// Below is a simple example of exporting a C++ function to R. You can
// source this function into an R session using the Rcpp::sourceCpp 
// function (or via the Source button on the editor toolbar)

// For more on using Rcpp click the Help button on the editor toolbar

// [[Rcpp::export]]
int timesTwo(int x) {
   return x * 2;
}

对此有何帮助?或者我应该遵循// [[Rcpp::plugins(cpp11)]]方法吗?

更新:使用attributes::sourceCpp()

devtools::install_github("Rcpp11/attributes")

然后从干净的会话重启:

library(Rcpp11)
attributes::sourceCpp("egfile.cpp") # in home directory.

我明白了:

据推测,您正在尝试从R Studio编译它,它将使用Rcpp::sourceCpp。您需要从sourceCpp包中实现attributes以生成Rcpp11的粘合代码。 attributes可从github获得:

devtools::install_github("Rcpp11/attributes")

然后使用此版本编译您的文件,即

attributes::sourceCpp( "yourfile.cpp" )

使用Rstudio ui编译Rcpp11文件是我们尚未处理的内容,但我们根据需要确定了here
