Classification Methods in R

We used classification methods to determine, for example, how marketing should be placed or how it should be adapted.  Most of this work was done long before R, but with adapted codes,  I am still in the process of understanding of how some of these methods have been implemented in R.  So I am collecting examples for possible test.  Here in DSC, a collection of examples of classification in R. Among these, we used only a handful.  Instructive.
