Ooops, wrong JIT! Dirk is absolutely right. I meant to say see enableJIT is the compiler package, see <a href="http://www.r-statistics.com/2012/04/speed-up-your-r-code-using-a-just-in-time-jit-compiler/">http://www.r-statistics.com/2012/04/speed-up-your-r-code-using-a-just-in-time-jit-compiler/</a> <div>

I actually used to provided a patched binary for this within Debian. This was<br>
ahead of its time (ginve the renewed interest in JITs from LLVM and other<br>
places) and quite useful, but Ra/jit is at this point a dead project.<br>
