R function to return the order of sorted elements in an unordered vector?

Question

I just want to determine the indices of elements of an unsorted vector in an order and let say the order is from lowest to highest.

Example:

vec <- c(14, 50, 10, 41, 9)

return_indices(vec)

5 3 1 4 2 

I think there is an easy way to achieve this... 

Answer 1

In R programming you can simply achieve your goal with the help of sort and match():

match(sort(vec), vec)

#[1] 5 3 1 4 2
