In this presentation, I will convey how one programming language, R, has not only provided an abundance of advantages, but has transformed the way I see data analysis. R is a free program with thousands of add-in packages capable of doing a majority of basic and advanced statistical techniques and graphics. By investigating a hypothetical data set through cluster analysis, I will present how 1) defining custom functions efficiently allows for iterative exploratory investigations, 2) programmatic loops can perform millions of analyses in seconds, 3) relatively sim...
