A good resource on Data Mining using R environment is “Data Mining – Desktop Survival Guide” by Graham Williams. Its a well researched and frequently updated free online book. Graham does a good job of going through the data mining process and provides detailed descriptions of the commonly used algorithms.

Exmaples are in R (all with R source code, of course), with some good examples of graphical visualization as well.

R Environment is a part of DecisionStudio-Professional and can also be separately downloaded from http://r-project.org.

On Friday we released DecisionStudio Professional – a comprehensive and free desktop BI Platform that gives you all the tools needed for analytics under a single package licensed under GNU Public License (GPL).

DecisionStudio Professional (DSP) is an advanced graphical data mining, reporting, modeling, and analysis environment built on top of the best-of-breed open source projects. Some of these include:
— Optimized MySQL database as data warehouse platform
— SQL Workbench (MySQL Query Browser and DBDesigner) for Data Analysts
— R environment for statistical analysis and modeling
— iReport Reporting GUI and JasperReport reporting library
— Python with Boa Constructor IDE for application and GUI development

DecisionStudio Professional is the only end-to-end open source analytics platform that provides comprehensive capabilities to each role. Data Analysts get to store, process, and publish data on a standard MySQL platform; Reporting Analysts would like iReport and the integration with Office tools; and Modelers would love the excellent R Environment. It also includes Python along with a drag-n-drop GUI building environment for analytics Application Developers.
