How to use it

with cppFunction

Pass "RcppThread" to the depends argument and "cpp11" to the plugins argument. For example:

Rcpp::cppFunction('void func() { /* actual code here */ }', 
                       depends = "RcppThread", plugins = "cpp11")
with sourceCpp


// [[Rcpp::plugins(cpp11)]]
// [[Rcpp::depends(RcppThread)]]

before including any headers in your source code.

in another R package
  1. Add the line CXX_STD = CXX11 to the src/Makevars(.win) files of your package.
  2. Add RcppThread to the LinkingTo field of your DESCRIPTION file.

Automatic override of std::cout and std::thread

There are preprocessor options to replace all occurences of std::cout and std::thread with calls to RcppThread::Rcout and RcppThread::Thread (provided that the RcppThread headers are included first). To enable this, use

#define RCPPTHREAD_OVERRIDE_COUT 1    // std::cout override
#define RCPPTHREAD_OVERRIDE_THREAD 1  // std::thread override

before including the RcppThread headers.
