#include <Rcpp11> file not found error

Question

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 ?

Update: using the attributes::sourceCpp()

devtools::install_github("Rcpp11/attributes")

then restart from a clean session:

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

I get:

I have change the tag from rcpp to rcpp11. – Easily

And there is no such thing as plugin=Rcpp11 – Easily

Answer 1

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

Easily

Great guessing -- sorry for the ambiguity in my question. I have modified it accordingly. Please see the update as doing this brings about compile errors. Thanks for this early support, very excited about new header-only package. – Adaptation

The new errors you mentioned were I believe fixed yesterday between builds 370 and 371. See travis-ci.org/Rcpp11/Rcpp11/builds There were a few errors in between, but the current snapshot builds. – Easily

Also @user3686430 welcome on Stack Overflow. You'll get better answers if you identify yourself with your profile (e.g. instead of some random user name). If my answer suits you, please consider accepting it (the tick mark next at the top left). – Easily

I have the identical problem to the original poster. Tried this solution. However, the function attributes::sourceCpp() fails with an error. These comments are from 2014, could you give me a heads up if this answer is still supposed to be valid? Thanks! – Tinsel
