Sorry, here is the code:
> x <- ts(1:12)
> y <- ifelse(rep(TRUE, 12), x, x)
> str(x)
Time-Series [1:12] from 1 to 12: 1 2 3 4 5 6 7 8 9 10 ...
> str(y)
int [1:12] 1 2 3 4 5 6 7 8 9 10 ...

The problem is that ifelse strips attributes. For example, consider
this which has nothing to do with factors but illustrates the point
with ifelse:

Time-Series [1:12] from 1 to 12: 1 2 3 4 5 6 7 8 9 10 ...

int 1

I want to change all "minus" to "b". I know that the simplest way to do this is
> levels(x) <- c("b", "f", "b")
and also that

works. But why not
