History
In the early 1990s, Richard Becker and William Cleveland (two researchers at Bell Labs) built a revolutionary new system for displaying data called Trellis graphics. (You can find more information about the Trellis software at http://cm.bell-labs.com/cm/ms/departments/sia/project/trellis/.) Cleveland devised a number of novel plots for visualizing data based on research into how users visualize information.[41]
The lattice package is an
implementation of Trellis graphics in R.[42] You may notice that some functions still contain the
Trellis name. The lattice package
includes many types of charts that will be familiar to most readers
such as scatter plots, bar charts, and histograms. But it also
includes some plots that you may not have seen before such as dot
plots, strip plots, and quantile-quantile plots. This chapter will
show you how to use different types of charts, familiar and
unfamiliar, in the lattice package.

[42] It’s not exactly the same as the S version, but unless you want to use old S/S+ code, the differences will probably not matter to you.
