I have found a strange "ifelse" behaviour (I think)
This works:
> ifelse(T,1+1,1+2)
[1] 2
> ifelse(F,1+1,1+2)
[1] 3
Maybe I missed something about R internals, but why
> ifelse(T,print("hello"),print("goodbye"))
[1] "hello"
[1] "hello"
> ifelse(F,print("hello"),print("goodbye"))
[1] "goodbye"
[1] "goodbye"
values are returned two times? I'm not sure: if it's a bug I'll post it
immediately
Thank You
Luca
