R is a programming language similar to S, designed for statistical computing and graphics. R is a GNU project developed at Bell Laboratories, with the first version launched in 2000. This paper is a demonstration of different graphing applications that can be accomplished through the R programming language. The majority of the focus will be on the analysis of stock market information in R.
The starting point for this paper is with the first project that was conducted: a scatterplot combining aesthetic elements. With a basic code, the project added a creative twist to graphing in R. The outcome of this project was a scatterplot graphing heartweight and bodyweight of male and female cats. This project was found on R-Bloggers, and changes were made accordingly to the code. Instead of using normal points on the graph, the dots were replaced with .png images of cats. This provided a fun, visual example that made differentiating between male and female cats easier, therefore allowing for easier analysis of trends based on the sex of the cat. A linear regression trend line is also implemented, with paw prints, to further illustrate the correlation between the data.
