S-Plus On Unix

Invoking S-plus

At the Unix prompt, type Splus. To get out you type q().

Note that UNIX commands are case-sensitive. The command Splus will invoke the software, but the command sPlus or SPLUS will not.

Storing Objects

Before we start S-Plus we need to deal with the question where S-Plus will store everything. Because S-Plus is object oriented, you will generate a lot of files (objects). The first time you invoke S-Plus it will create a folder called .Data (or MySwork, on some systems) at the top level of your unix account ( /u/fred/.Data).

If you do a lot of statistical programming, you will probably want to create multiple .Data directories in different folders. You can do this using the unix mkdir command.
