[R] naming vectors

[Ivan Calandra]

It is indeed an interesting behavior and I have no idea what you could 
do except what you did, though I would use:
names(x) <- rep("A", length(x))

But I don't really understand why you want to give the same name to all 
elements? There might be another way around depending on your goal
