Agreed, Python scales down and so is also good for small tasks. What I was saying is that Ruby - as much as I like it - does not generally scale up beyond a certain point.

Both R and Ruby have had issues with large data sets which have been addressed to some degree in more different distributions and more recent releases. Python is ready out of the box for large data sets. So what I meant to communicate is that if you know that you are going to be dealing with a large data set, you might as well go straight to python.
