Book description
This O’Reilly cookbook provides more than 150 recipes to help scientists, engineers, programmers, and data analysts generate highquality graphs quickly—without having to comb through all the details of R’s graphing systems. Each recipe tackles a specific problem with a solution you can apply to your own project and includes a discussion of how and why the recipe works.
Most of the recipes in this second edition use the updated version of the ggplot2 package, a powerful and flexible way to make graphs in R. You’ll also find expanded content about the visual design of graphics. If you have at least a basic understanding of the R language, you’re ready to get started with this easytouse reference.
 Use R’s default graphics for quick exploration of data
 Create a variety of bar graphs, line graphs, and scatter plots
 Summarize data distributions with histograms, density curves, box plots, and more
 Provide annotations to help viewers interpret data
 Control the overall appearance of graphics
 Explore options for using colors in plots
 Create network graphs, heat maps, and 3D scatter plots
 Get your data into shape using packages from the tidyverse
