I have a Python background and recently signed for the Coursera course on R that just started (https://www.coursera.org/course/compdata) because I wanted to get a small taste of R and see how it differed from Python's scientific computing stack.

So right now I'm not far enough in the learning curve to see all the benefits R provides. Is it worth investing time in R now if I'm already pretty familiar with a good amount of the Python ecosystem? Or, would it make more sense to continue on in Python?
