What is the difference between sort () and sort.list () in R?

Well, having decided to get acquainted with some of the basic functions in R, I came across a function sort.list(). I get a pretty straightforward function sort(), but don't understand the idea sort.list(). I read that this should be a permutation function reordering the contents of my vector (in some way).

Having a vector

x <- c(5.0, 3.0, 2.0, 2.2, 0.0, 5.0, 3.0, 2.0, 2.2)

Execution of sort.list(x)exits

[1] 5 3 8 4 9 2 7 1 6

Where did it come from? Can someone give me a hint please? And what use is this permutation anyway?

Thank.

sort.list, as said in ?sort.list, coincides with order, only instead of accepting several arguments through ...it takes only one atomic vector as an argument.

, " " " " order.

? :

x <- c(5.0, 3.0, 2.0, 2.2, 0.0, 5.0, 3.0, 2.0, 2.2)
> x[sort.list(x)]
[1] 0.0 2.0 2.0 2.2 2.2 3.0 3.0 5.0 5.0
> x[order(x)]
[1] 0.0 2.0 2.0 2.2 2.2 3.0 3.0 5.0 5.0
