Question

Assume the variable books_vector is a vector that contains six elements. Which of the following commands creates an array of this vector with three rows and two columns?

 
**Question:**

Assume the variable `books_vector` is a vector that contains six elements. Which of the following commands creates an array of this vector with three rows and two columns?

**Options:**

- ○ `array(books_vector, dim = c(3,2))`

- ○ `array(books_vector, dim = c(2, 3))`

- ● `array(books_vector, dim = c(3, 2))`

- ○ `array(c(books_vector), dim = (2, 3))`

**Explanation:**

The correct choice is the third option:

- `array(books_vector, dim = c(3, 2))`

This command will create an array with the specified dimensions of three rows and two columns, utilizing all six elements of `books_vector`.
