[R] !!!function to do the knn!!!

Thank your for your entry in the Poorly Capitalized and Inadequately  
Searched Posting Contest. You will be advised of your ranking in due  
course. In the meantime, you may want to consult the recommended  
search site for []functions and []Task Views  that have "clustering"  
and "classification" in their text:

http://search.r-project.org/cgi-bin/namazu.cgi?query=classification+clustering&max=100&result=normal&sort=score&idxname=functions&idxname=views

I originally set the parameters at just "classification" in []Task  
Views and []functions but that list was too long.
