functional programming part

[AlainVagner]

Just a few comments reading the page about functional programming, not an issue per se:

• When speaking about recursive functions, I am wondering if it could be interesting to mention the special case of tail recursion. I have found the tailr package to manage the tail call optimization of these functions, but it does not seem to be maintained anymore.
• What about curried functions in R?
• As I understood, most data structures in R are immutable. Might be interesting to mention it?
• When you mention the maybe monad, I would have been interested to see how you manage this in the frame of a pipe, how you can substitute a default value to Nothing(), etc.

I have seen that you wrote another book on this topic, I will just check this other book :)
