Is the FoldLeft function available in R?
- by JSmaga
Hi,
I would like to know if there is an implementation of the foldLeft function (and foldRight?) in R.
The language is supposed to be "rather" functional oriented and hence I think there should be something like this, but I could not find it in the documentation.
To me, foldLeft function applies on a list and has the following signature:
foldLeft[B](z : B)(f : (B, A) => B) : B
It is supposed to return the following result:
f(... (f(f(z, a0), a1) ...), an) if the list is [a0, a1, ..., an].
(I use the definition of the Scala List API)
Does anybody know if such a function exists in R?
