write R code to create the following vectors:

1. name of the vector: StudentNames; values in the vector: Gene, Sam, Jess, Alex, Justin

2. name of the vector: GPA; values in the vector: 3.5, 4.0, 3.2, 3.7, 3.5

3. name of the vector: Major; values in the vector: ACCTG, FIN, BSAN, BSAN, MKTG

Write R code to create a data frame (name of the data frame should be classBSAN) using the vectors created in Question 1.

What is the class of "Major" column in your "classBSAN" data frame?

Write an R code to list all the levels in the "Major" column.
