Well, with Haskell you don't have to load the whole data set into
memory, as Michael shows. With R, on the other hand, you do.

Besides, if you're not an R expert, and if the analysis you want to do
is not readily available, it may be quite a pain to implement in R.

As a simple example, I still don't know an acceptable way to write
something like zipWith f (tail vec) vec in R.
