# OOP in R: A Short Tutorial on S4 Class

This is a hands-on tutorial about OOP in R, giving a short tutorial about S4 class.

Note that S4 class is just one of at least four R’s object systems available to the R programmers: S3, S4, R5, and R6.

The famous Biocunductor folks makes heavy use of S4 classes, but Google, on the other hand, advise to “avoid S4 objects and methods when possible”. Read more OOP in R: A Short Tutorial on S4 Class

# Financial Engineering Lecture 1: Course Overview

This lecture is the overview of this course of financial engineering.

## Overview

Financial Engineering is a multidisciplinary field drawing from finance and economics, mathematics, statistics, engineering and computational methods. The emphasis of FE & RM Part I, lectures 1~10, will be on the use of simple stochastic models to price derivative securities in various asset classes including equities, fixed income, credit and mortgage-backed securities. We will also consider the role that some of these asset classes played during the financial crisis. A notable feature of this course will be an interview module with Emanuel Derman, the renowned “quant” and best-selling author of “My Life as a Quant.” We hope that students who complete the course will begin to understand the “rocket science” behind financial engineering but perhaps more importantly, we hope they will also understand the limitations of this theory in practice and why financial models should always be treated with a healthy degree of skepticism. The follow-on course FE & RM Part II, lectures 11~20, will continue to develop derivatives pricing models but it will also focus on asset allocation and portfolio optimization as well as other applications of financial engineering such as real options, commodity and energy derivatives and algorithmic trading.
