Wu et al. describe top 10 algorithms in data mining in (LDO) "Top 10 algorithms in data mining" (2007). How to use these algorithms in R is shown here. The datasets used are available in R itself, no need to download anything. Run data() to see the available datasets. Nothing is original here, everything was Googled, and no references are made to sources. The purpose of all this is to show how quickly you can prototype most algorithms with minimal code, in R.
