R Program to Sort a Vector
In this example, you’ll learn to sort a vector in R using sort() function.
Sorting of vectors can be done using the
sort() function. By default, it sorts in ascending order. To sort in descending order we can pass
Note that sort is not in-place. This means that the original vector is not effected (sorted). Only a sorted version of it is returned.
Example: Sort a Vector
> x  7 1 8 3 2 6 5 2 2 4 > # sort in ascending order > sort(x)  1 2 2 2 3 4 5 6 7 8 > # sort in descending order > sort(x, decreasing=TRUE)  8 7 6 5 4 3 2 2 2 1 > # vector x remains unaffected > x  7 1 8 3 2 6 5 2 2 4
Sometimes we would want the index of the sorted vector instead of the values. In such case we can use the function
> order(x)  2 5 8 9 4 10 7 6 1 3 > order(x, decreasing=TRUE)  3 1 6 7 10 4 5 8 9 2 > x[order(x)] # this will also sort x  1 2 2 2 3 4 5 6 7 8
