Exploring Data

In the preceding chapters, we have laid the foundation for understanding the concepts and ideas of the S-Plus system. We explored basic ideas and how to use S-Plus for performing calculations, and we have seen how data can be generated, stored, and accessed. Furthermore, we also looked at how data can be displayed graphically. All this will be useful as we explore real data sets and learn how to use the existing functionality of S-Plus in this chapter. We will explore data sets that come with S-Plus, specifically the Barley and Geyser data sets.
