Enter plot(rules) to display the scatterplot of the 2,918 rules ( Figure 5.3 ) ,
where the horizontal axis is the support, the vertical axis is the confidence, and the
shading is the lift. The scatterplot shows that, of the 2,918 rules generated from the
Groceries dataset, the highest lift occurs at a low support and a low confidence.

minimum confidence 0.6
Entering plot(rules@quality) displays a scatterplot matrix ( Figure 5.4 ) to
compare the support, confidence, and lift of the 2,918 rules.
