Chapter 15. Lattice Graphics
The lattice
package provides a
different way to plot graphics in R. Lattice graphics look different
from standard R graphics, are created with different functions, and have
different options. Lattice functions make it easy to do some things that
are hard to do with standard graphics, such as plotting multiple plots
on the same page or superimposing plots. Additionally, most lattice
functions produce clean, readable output by default. This chapter shows
what lattice graphics can do and explains how to use them.
The real strength of the lattice
package is in splitting a chart into
different panels (shown in a grid), or groups (shown with different
colors or symbols) using a conditioning or grouping variable. This chapter includes many examples
that start with a simple chart and then split it into multiple pieces to
answer a question raised by the original plot.
