Transcribed Image Text:**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`.
