Consider the vector x: x < - c (2, 43, 27, 96, 18) Match the following outputs to the function which produces that output. Options include sort (x), order (x), rank (x) and none of these

Completed Question

Outputs to be matched to the functions are:

1,2,3,4,5 1,5,3,2,4 1, 4, 3, 5, 2 2, 18, 27, 43, 96

Answer:

sort (x) : 2, 18, 27, 43, 96 order (x) : 1, 5, 3, 2, 4 rank (x) : 1, 4, 3, 5, 2 none of these : 1, 2, 3, 4, 5

Step-by-step explanation:

Given the vector x: x < - c (2, 43, 27, 96, 18)

Sort

In R, the sort (x) function is used to arrange the entries in ascending or descending order. By default, R will sort the vector in ascending order.

Therefore, the output that matches the sort function is:

sort (x) : 2, 18, 27, 43, 96

Rank

The rank function returns a vector with the "rank" of each value.

x < - c (2, 43, 27, 96, 18)

2 has a rank of 1 43 has a rank of 4 27 has a rank of 3 96 has a rank of 5 18 has a rank of 2

Therefore, the output of rank (x) is: 1, 4, 3, 5, 2

Order

When the function is sorted, the order function gives the previous location of each of the element of the vector.

Using the sort (x) function, we obtain: 2, 18, 27, 43, 96

In the vector: x < - c (2, 43, 27, 96, 18)

2 was in the 1st position 18 was in the 5th position 27 was in the 3rd position 43 was in the 2nd position 96 was in the 4th position

Therefore, the output of order (x) is: 1, 5, 3, 2, 4
