 Hi I need some help with ploting the ROC for K-nearest neighbors. Since KNN
 is a non-parametric classification methods, the predicted value will be
 either 0 or 1.
 It will not be able to test for different cutoff to plot ROC. What is the
 package or functions I should use to plot ROC for KNN?
 
 Thanks.
