Directions

This pre-class assignment should be completed by 8:00am on 01-15-19. Reproduce this entire document using R Markdown. Formatting and style should match exactly. Once you are done, don’t forget to complete the survey.

To get started, go to File \(\rightarrow\) New File \(\rightarrow\) R Markdown.

R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

summary(cars)

##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00  
##  1st Qu.:12.0   1st Qu.: 26.00  
##  Median :15.0   Median : 36.00  
##  Mean   :15.4   Mean   : 42.98  
##  3rd Qu.:19.0   3rd Qu.: 56.00  
##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

Syntax

Let’s showcase the different header levels.

Level 1 header

Level 2 header

Level 3 header

Level 4 header

Level 5 header

Level 6 header

I can make my narrative bold, italicized, or plain.

You can use LaTeX syntax. Equations can be displayed, such as \[P(A \cup B) = P(A) + P(B) - P(A \cap B)\] or in-line such as \(P(A \cup B) = P(A) + P(B) - P(A \cap B)\).

Two excellent books with regards to R

R for Data Science
R Cookbook

My top three favorite books in finance are

Liar’s Poker
When Genius Failed: The Rise and Fall of Long-Term Capital Management
The Smartest Guys in the Room: The Amazing Rise and Scandalous Fall of Enron

Below is some code to make a quick HTML table based on a data frame. The function kable is part of the package knitr.

knitr::kable(head(mtcars))
