#include <Rcpp11> file error not found

I am trying to use the Rcpp11 package in r from its source through:

 devtools::install_github("Rcpp11/Rcpp11")

I read here: http://blog.r-enthusiasts.com/2014/05/27/disambiguating-rcpp11-and-rcpp/

that I can use include <Rcpp11> + using namespace Rcpp11 at the head of my .cpp file, but I get this error when searching:

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

where 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; }

Any help with this? or should I refer to the method // [[Rcpp::plugins(cpp11)]] ?

Update: using attributes::sourceCpp()

 devtools::install_github("Rcpp11/attributes")

then reboot from a clean session:

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

I get:

Presumably, you are trying to compile it from R Studio, which will use Rcpp::sourceCpp . To create glue code for Rcpp11, you will need the implementation of sourceCpp from the attributes package. attributes available from github:

 devtools::install_github("Rcpp11/attributes")

Then use this version to compile your file, i.e.

 attributes::sourceCpp( "yourfile.cpp" )

Compiling an Rcpp11 file using Rstudio ui is something that we have not yet considered, but something that we have identified as necessary here
