English | 2018 | ISBN: 978-1789612158 | 140 Pages | EPUB | 51 MB

Develop informative and aesthetic visualizations that enable effective data analysis in less time
Applied Data Visualization with R and ggplot2 introduces you to the world of data visualization by taking you through the basic features of ggplot2. To start with, you’ll learn how to set up the R environment, followed by getting insights into the grammar of graphics and geometric objects before you explore the plotting techniques.
You’ll discover what layers, scales, coordinates, and themes are, and study how you can use them to transform your data into aesthetical graphs. Once you’ve grasped the basics, you’ll move on to studying simple plots such as histograms and advanced plots such as superimposing and density plots. You’ll also get to grips with plotting trends, correlations, and statistical summaries.
By the end of this book, you’ll have created data visualizations that will impress your clients.
