Visualizing Your Data
Andrew P. Beckerman, Dylan Z. Childs, Owen L. Petchey · Oxford University Press eBooks · 2017
Looking at your data is about the most important thing you can do. A good graph will often tell you the answer to your question, and statistics will then just confirm what you already see. We always plot our data first. We focus on teaching you how to use the add-on package ggplot2 for creating beautiful graphs. You learn how to make simple and complex scatterplots, histograms, and box-and-whisker plots and some basic customization of these. You also learn how to use the graphs in presentations and reports.
