Realistically, rather than work with the fussy syntax of this pseudo functional language, most people who work in data science would be better of using Python because of the IPython Notebook http://ipython.org/notebook.html http://ipython.org/notebook.html which provides similar mixing of code and graphical results. The matplotlib, inspired by Mathematica, can produce a wide variety of graphical plots. Newer libraries like pandas have been bringing all the power of R into the Python world. Five years ago, Wolfram may have been worthwhile, but today the wave has formed and it is converging on Python.
