Creating plots with the lattice package
The lattice package produces Trellis plots to capture multivariate relationships in the data. Lattice plots are useful for looking at complex relationships between variables in a dataset. For example, we may want to see how y changes with x across various levels of z. Using the lattice package, we can draw histograms, boxplots, scatterplots, dot plots and so on. Both plotting and annotation are done in one single call.
