I just encountered this link.
It talks about how julia is faster than r and python. And the person poses a question if R can be fast enough by using the same techniques. Its a must read link. And the answer that he gets is there are projects for making it faster.
I googled it and found projects like RHO. But they are not being worked upon.
So my question is this what and how many (if there are any) projects are trying to make R more faster. And can we implement an LLVM COMPILER in R as well.
