ABSTRACT
This chapter introduces a few of the most important features of the S-PLUS command language, leaving a more detailed account to be given in Appendix A. The graphical user interface (GUI) allows routine analyses to be carried out by simply completing various “dialog boxes,” and graphs to be produced and edited by a “point-and-click” approach. S-PLUS is a language designed for data analysis and graphics developed at AT&T’s Bell Laboratories. The S-PLUS language also provides the facility for creating functions for specific analyses of interest. Use of the GUI involves menus, dialog boxes, and point-and-click graphics. For example, many statistical techniques can be applied in S-PLUS by using the Statistics Menu and then filling in the relevant dialog box. The GUI approach to producing S-PLUS graphics is extensive and flexible, and can involve either the use of dialog boxes from the Graphics Menu, or the Graphics palettes.
