S-PLUS 3.3 introduces new Windows features, as well as enhanced graphics tools in the Trellis Display Graphics Library. Survival analysis tools, an object-oriented matrix library, and data frame functions have also been added. Users also have access to tools within S-PLUS that support effective session management and workflow. A time-saving session command history file creates an editable record for easy verification and duplication of commands. Customizable menus and dialog boxes allow the user to bypass the command line and specify data and operations via an interface with menus, templates and forms.
Trellis allows users to create highly visual graphic displays of multi-variate data.
New Trellis capabilities include animation and color draping. S-PLUS 3.3 incorporates new survival analysis routines developed by Dr. The matrix library allows users to perform object-oriented numerical linear algebra. New data frame functions added to S-PLUS include merging data frames and repeating analyses by each level of a given factor variable. S-PLUS permits combining objects into data frames, and the easy extension of data frame coercion to handle new data types.
