R-Friendly Multi-Threading in C++

Calling multi-threaded C++ code from R has its perils. Since the interpreter is single-threaded, one must not check for user interruptions or print to console multiple threads. One can, however, synchronize with main thread. The package RcppThread (current version 1.0.0) contains a header only library thread safe communication that exploits this fact. It includes classes threads, pool, and parallel loops routinely R. This article explains package's functionality gives examples of usage. synchronization mechanism may also apply other threading frameworks. Benchmarks suggest that, although causes overhead, abstractions are competitive popular libraries in typical scenarios encountered statistical computing.
