title: Linking R and Julia?
body: <p>Julia looks very promising for fast and syntax-sane computation (e.g. <a href="http://www.johnmyleswhite.com/notebook/2012/03/31/julia-i-love-you/" rel="noreferrer">here</a>), but I suspect it will not be anywhere near R in terms of overall statistics workflow for some time yet.  So I'd like to use it where C++ is mainly used in R programs: to optimize slow portions of code.  Before I invest the time in learning Julia, though, I am curious what facilities there are for embedding Julia snippets in R code.</p>
  
  <p>So:</p>
  
  <ul>
  <li>What facilities are out there for linking R and Julia?</li>
  <li>How robust and well-thought-out are they, on a scale of zero to Rcpp?</li>
  </ul>
  
  <p>I want to call Julia from R, just as Rcpp allows calling C++ from within R right now.  I do not want to call R from Julia. (So RCall.jl would not work)</p>
