You need to study ?order and perhaps also subscripting. If that isn't sufficient, I suggest you consult one of the many R web tutorials that cover this.
Perhaps this will help: x[order(x)] gives x in sorted order, which is what you woud get with sort(x). Indeed, the code implementing sort.default(x) is essentially x[order(x)] !
