Suppose there was a basis for and a certain number of dimensions for subspace W in $\mathbb{R}}^{4$ .Why is the number of dimensions 2?

$W=\{\u27e84s-t,s,t,s\u27e9\mid s,t\in \mathbb{R}\}$

For instance, apparently,$\{\u27e80,1,4,1\u27e9,\u27e81,1,3,1\u27e9\}$

is a valid set, and it happens to be of dimension 2 in$\mathbb{R}}^{4$ . Does a basis for $\mathbb{R}}^{n$ have to have n vectors?
