R: Data Analysis and Visualization

Chapter 1. R Graphics

R provides a number of well-known facilities that produce a variety of graphs to meaningfully visualize data. It has low-level facilities where we deal with basic shapes to draw graphs and high-level facilities. There are functions available here to produce quality graphs; these functionalities are usually developed using certain combinations of basic shapes. Using R, we can produce traditional plots, the trellis plot, and very high-level graphs inspired by the Grammar of Graphics implemented in the ggplot2 package. The default graphics package is useful for traditional plots, lattice provides facilities to produce trellis graphs, and the ggplot2 package is the most powerful high-level graphical tool in R. Other than these, ...
