[R] A problem with order() function in R

[Bert Gunter]

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)] !

Cheers,
Bert
