Free Tools for Data Mining

I got to know about RapidMiner and thought of testing it out (under progress). Tried K-Means clustering. The selection of raw data / input file was pretty easy, then I tried to link the process to K-means.  +RapidMiner threw an error that there were some missing values (also suggested to select a method/process that is available for missing value imputation.

I added the process (refer figure below) and then linked the process back to the +KMeans. So far so good. Wanted to know more from statisticians and analysts who have used  Open Source Software - like R,  and also SAS,   +Microsoft Dynamics ERP and SPSS
