Again, it's sort of like COBOL: it's dying, but until it's dead, there's a lot of money to be made maintaining old macro libraries etc for dinosaur companies.
If anyone brings up the FDA... Just don't do that ok?
You may be waiting for a while. The thing that R has going for it is documentation. The thing it has going against it is the monstrosity of the language implementation.
Julia is nice if you're coming from Matlab. And it sure as hell is more efficient than R or Python. But the libraries just aren't there yet. I went to implement dropout regularization a while back (a year or two ago?) and there were just so many things that I take for granted in R and Python that were completely missing. I mean, yeah it's fun to write your own SGD implementation... Once... Per lifetime...
