Hello again,
Let say I have following user defined function:
fn <- function(x, y) {
Vec1 <- letters[1:6]
Vec2 <- 1:5
return(list(ifelse(x > 0, Vec1, NA), ifelse(y > 0, Vec2, NA)))
}
Now I have following calculation:
> fn(-3, -3)
[[1]]
[1] NA
[[2]]
[1] NA
> fn(3, -3)
[[1]]
[1] "a"
[[2]]
[1] NA
Here I can not understand why in the second case, I get only the first
element "a" of the corresponding vector 'Vec1'? I want to get complete
vector(s) as the function return.
Can somebody help me how to achieve that?
Thanks and regards,
