| Title: Tools and Classes for Statistical Models | ||
| Date: $Date: 2006-11-03 11:17:22 +0100 (Fri, 03 Nov 2006) $ | ||
| Version: 0.2-9 | ||
| Author: Torsten Hothorn, Friedrich Leisch, Achim Zeileis | ||
| Date: $Date: 2007-01-11 18:42:45 +0100 (Thu, 11 Jan 2007) $ | ||
| Version: 0.2-10 | ||
| Author: Torsten Hothorn, Friedrich Leisch, Achim Zeileis | ||
| Maintainer: Torsten Hothorn <Torsten.Hothorn@R-project.org> | ||
| Description: A collection of tools to deal with statistical models. | ||
| The functionality is experimental and the user interface is likely to | ||
| change in the future. The documentation is rather terse, but packages `coin' | ||
| and `party' have some working examples. However, if you find the | ||
| implemented ideas interesting we would be very interested in a discussion | ||
| of this proposal. Contributions are more than welcome! | ||
| Depends: R (>= 2.0.1), methods, stats | ||
| Depends: stats, stats4 | ||
| Imports: methods | ||
| SaveImage: yes | ||
