It's not clear what you mean by "some parts of the function output".
The function output is whatever you nominate it to be, and can
include any selection of whatever was computed within the function.

For example:

  testfn <- function(x){
    X <- x^2 ; Y <- cos(X) ; Z <- (X + Y)/(1 + x)

# [1] 1.210000 0.744295

However, I suspect your case may be a bit more complicated than that!
If you were to post the function (or something like it), explaining
what you want it to return, and in what way it returns what you do
not want, it would be easier to help.
