[R] order function give back row name

[Sarah Goslee]

With similar data, since you didn't include reproducible example of your own:

> results <- matrix(c(53, 55, 37, 83), nrow=1)
> colnames(results) <- letters[1:4]
> results
      a  b  c  d
[1,] 53 55 37 83
> order(results)
[1] 3 1 2 4
> colnames(results)[order(results)]
[1] "c" "a" "b" "d"
