A First Session

Abstract

The remainder of the book is devoted to the use of S-Plus via the command line. We will look at how to use S-Plus as a calculator for simple and complex calculations. We will look at different data structures and how to handle data flexibly. We will generate graphs displaying data and mathematical functions, explore data sets in detail, and use statistical models. Finally, we will import data in several ways, automatize tasks by writing functions, and investigate many details that can help a lot in practice.
