SPlus 5.1 Now Available on IBM RCS Machines

Version 5.1 of SPlus, a data analysis package that provides interactive analysis with step-by-step feedback using a built-in object-oriented language, is now available on all IBM AIX RCS workstations.

To use this newest version of the package, enter the following commands from a UNIX prompt on any IBM AIX RCS machine:

     setup splus-new
     Splus5

SPlus 5.1 includes the following features:

• Resampling methods including bootstrap and jackknife estimation

• Multiple comparisons

• Power and sample size calculations

• Improved cluster analysis and robust regression functions

• A new help system

• Better support for large data objects

• A better Object-Oriented Programming model

• Improved data import and export capabilities

• An improved mechanism for loading C and Fortran code

• Improved date, time, and time series support

• Support for the World Wide Web

To access a list of SPlus' built-in on-line help topics, enter the following command at the > SPlus prompt:

     help.start()

Doing this will start up Netscape, and open an S-Plus help window containing links to numerous SPlus functions, datasets, and categories.

To exit the SPlus program, use the CTRL-D key sequence.

SPlus 5.1 will become the default version on December 27, and you will no longer have to set it up. You will still be able to access the old version, SPlus 3.4, until Tuesday, February 1, 2000, by entering the command setup splus-old from a UNIX prompt before running the program.

If you have any questions, problems, or comments about using SPlus, please contact the ACS Help Desk consultants by phoning ext. 7777, or by directing electronic mail to consult@rpi.edu.
