Software

Rattle (the R Analytical Tool To Learn Easily) provides a simple and logical interface for data mining. It is a new data mining application based on the widley used, open source and free statistical language R using the Gnome graphical interface. The application runs under GNU/Linux, Macintosh OS/X, and MS/Windows. The aim is to provide an intuitive interface that readily takes you through the basic steps of data mining, as well as illustrating the R code that is used to achieve this. Whilst the graphical tool itself may be sufficient for all of a user's needs, it is also a stepping stone to more sophisticated processing and modelling in R, if so desired.
