S-Plus

S-Plus is an advanced and powerful programming language for data management, analysis and graphics. At Princeton S-Plus for Unix is available on the Arizona Unix server, as well as some other departmental Unix servers. S-Plus for Windows is also installed on the computers in the DSS lab. It is not easy to learn and would generally not be a first choice for students wishing to conduct an analysis. Support available for S-Plus at DSS and on campus is minimal.
