Build a plot layer by layer

  • Hadley Wickham
Part of the Use R book series (USE R)

Layering is the mechanism by which additional data elements are added to a plot. Each layer can come from a different dataset and have a different aesthetic mapping, allowing us to create plots that could not be generated using qplot(), which permits only a single dataset and a single set of aesthetic mappings.
