R Graph Essentials

R has undergone an explosion of popularity around the world. The wide range of graphs and options for creating high-impact visualizations makes R a highly effective tool for researchers, data analysts, students, and others.

This book starts with the basics of R and the principles of creating graphics, focusing on scatterplots and line graphs for research and data analysis.

After that you will learn how to include mathematical expressions on your graphs and create bar charts, histograms, boxplots, and so on using advanced functions. The book then dives deeper into shading and coloring your graphs and labeling points on graphs using the qplot function. After that you will learn how to use the ggplot package to control symbol color, size, shape, and many other attributes.

By the end of this book, you will have expert skills to create attractive and informative graphics and design professional-level graphs.
