We have learned the powerful approach to generating visualization with ggplot. However, there are instances in which all we want is to make a quick plot of, for example, a histogram of the values in a vector, a scatterplot of the values in two vectors, or a boxplot using categorical and numeric vectors.

The ggplot2 library is a follow-up of the ggplot library, and stands for the ‘grammar of graphics’. It produces attractive, professional-looking graphics that are good, especially for presentations. This comes at a cost of some of the flexibility that standard R graphics give, but it is often worthwhile.
