I am attempting to use the Rcpp11 package in r from it's source over at:
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 upon sourcing:
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 defer to the // [[Rcpp::plugins(cpp11)]] method ?
attributes::sourceCpp()devtools::install_github("Rcpp11/attributes")
then restart 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. You need the implementation of sourceCpp from the attributes package to generate the glue code for Rcpp11. attributes is 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 we have not yet dealt with, but something we identified as needed here
