Dear UseRs,
please find below a simple example which exemplifies my question.
In words, I'd like to write a function which prints formula and outcomes only
when results are not assigned or recalling the already assigned object, as e.g.
glm.
I'm sure a solution is rather simple and straightforward and it has something
to do with match.call (maybe), but I'm not able to see it.
Thanks in advance for any help

# my simple function
myFUN <- function(a, b, method){
res <- ifelse(method==1, a+b, a-b)
object <- list(res=res, call=match.call())
return(object)
}
# assigning to A
A <- myFUN(2,4,1)
# recalling A or don't assign ...
A
myFUN(2,4,1)
# ... what I'd like (somehow) to have when
# I don't assign myFUN to another obj
# or when I recall the obj itself
My simple analysis
Call: myFUN(a = 2, b = 4, method = 1)
a: 2
b: 4
Outcome: 6
