I want to compute a function say 'name_sort' that takes the input names and values. The function should return the names from the second input - in decreasing order.

Thus values 3 2 1 should return the output A B and C

I am fairly new to R, so I am really struggling to wrap around my head if I am supposed to use an if statement or not. Any help would be much appreciated!

This is how I would like to start my statement:

names_sort <- function(values,names):

And this is the desired output

names_sort(c(3,1,2), c("A","B","C")) should return:

 [1] "A" "C" "B"

CodePudding user response：

We can use [ on ordering of values in descending

names_sort <- function(values, names) {names[order(-values)]}

-testing

> names_sort(c(3,1,2), c("A","B","C"))
[1] "A" "C" "B"
