User Contributed Software

We've collected on this page links to a number of S-PLUS related websites featuring software created by S-PLUS users. S-PLUS has a large and diverse user community, and you can find functions, packages, and example applications from a wide variety of industries in the links below.

These links are provided as a courtesy to the S-PLUS user community, but were not created by Insightful and therefore are not supported by us. Some packages may require older versions of S-PLUS to run. Any questions about software referenced below should be directed to the respective author.
