Rattle: A Graphical User Interface for Data Mining using R
From the webpage:
Rattle (the R Analytical Tool To Learn Easily) presents statistical and visual summaries of data, transforms data into forms that can be readily modelled, builds both unsupervised and supervised models from the data, presents the performance of models graphically, and scores new datasets.
I think I found Data Mining: Desktop Survival Guide before I located Rattle. Either way, both look like resources you will find useful.
