Hi Edgar, Thanks. "dprep" module works fine. However, I have one question. How does SFFS or SFS function know the class definition in the data? Function call doesn't require to specify the column that identifies the class type (as shown inthe example). Can you eleborate on this? Thanks.

Raj, look at academic.uprm.edu/eacuna/softw.htm, I built a library of R functions for data preprocessing tasks including feature selection for supervised classification. Please send me your comments. Edgar On Mon, 25 Oct 2004, Rajdeep Das wrote:
Hello, I want to do feature selection for classification purpose (using lda). Can someone point me to any R package or S-plus package for this? Something like SFS or SFFS method would be useful for me. Thanks. Raj [[alternative HTML version deleted]]
