我正在尝试Rcpp11从它的源代码中使用 r 中的包：
devtools::install_github("Rcpp11/Rcpp11")
我在这里读到：http ://blog.r-爱好者.com/2014/05/27/disambiguating-rcpp11-and-rcpp/
我可以在文件开头使用include <Rcpp11>+但在采购时出现此错误：using namespace Rcpp11.cpp
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;
}
有什么帮助吗？还是我应该遵循该// [[Rcpp::plugins(cpp11)]]方法？
更新：使用attributes::sourceCpp()
devtools::install_github("Rcpp11/attributes")
然后从干净的会话重新启动：
library(Rcpp11)
attributes::sourceCpp("egfile.cpp") # in home directory.
我得到：
