Dear all,
I have looked for an answer for a couple of days, but can't come with any
solution.
I have a set of functions, say:
> t0 <- function(x) {1}
> t1 <- function(x) {x}
> t2 <- function(x) {x^2}
> t3 <- function(x) {x^3}
I would like to find a way to add up the previous 4 functions and obtain a new
function:
> rrr <- function(x) {1+x+x^2+x^3}
without, actually, having to write it in the previous form (I could have cases
with hundreds of functions). I thought that perhaps I could first define a
list of functions:
> ttt <- list(t0,t1,t2,t3)
and then I could use something like "sum", to add up all the elements of the
list and obtain another function. I've tried:
> rrr <- function(x) {sum(ttt)}
but it does not work.
Any help with this is greatly appreciated.
Cheers,
james
