[R] Nesting Functions

[Manuel Morales]

Dear list members,

I'm looking for a way to write "nested" functions similar to the
function "Nest" or "NestList" in Mathematica.

E.g.,

f<-function(x) x+2*x

f(f(f(2)))

might instead be written as nest(f, 2, 3)

read as, nest function f 3 times with 2 as the initial value.

Thanks!

Manuel
