package with the command line:
library(lattice)
We can now have a look at the objects that are included in the package. This requires listing the loaded packages, which can be done by typing:
search()

The Lattice
package is number 2 in this list. This position can vary, depending on whether you have loaded other packages as well.
The ls()
function will allow us to inspect the content of lattice
(or any other loaded package), as we have seen in Chapter 1, Setting GNU R for Predictive Modeling. Because the lattice
package is in second position as just discussed, we type:
ls(2)
The output, composed of approximately 150 elements, is too long to be printed here. This illustrates the many graphing possibilities offered by lattice. We suggest you go through it on your screen. The idea is to get the feel of the...
