when I use the mode() function.
So what is it that assigning a mode does?

Not without changing the mode of v or the right hand side:
> v = vector(mode="numeric",length=10)

> v
[1] 0 0 1 0 0 0 0 0
It's useful when you need to be certain of the mode of a vector. One such
situation is when you are about to call a C-language function using the
.C() interface. As you point out, some assignments (even just to vector
elements) can change the mode of the entire vector. This is why it's
