My advice is Python, but it depends on what your background is and what you want to do. If this is your first language and you have a stats background, R is a solid choice. If you already know another language, R has a lot of flaws that are quite frustrating. Perhaps the worst thing about R is how hard it is to google answers to as opposed to Python. Like if you google R for loop, the first result http://www.r-bloggers.com/how-to-write-the-first-for-loop-in-r/ http://www.r-bloggers.com/how-to-write-the-first-for-loop-in... is much worse than the equivalent first result for python: https://wiki.python.org/moin/ForLoop https://wiki.python.org/moin/ForLoop
