S3 Objects and Functions in R

Understand R's S3 Object System and deepen your knowledge of R. This video breaks down base R object to the most fundamental aspects showing that a data.frame is just a list, a factor is an integer vector, and matrixes aren't real. Then learn how to write generic functions to create class specific functions using inheritance.
