Modifying function knnPredV () to take a general dataset with variable names and a formula for the variables to use in clustering: For this exercise, we will continue to use knnPredV () defined in the notes and listed below for reference (along with knnNat): ## knnMat definition set.seed (1234) y 1) {class - 0.5, 1, 0))}) } Modifying function knnPredV () to take a general dataset with variable names and a formula for the variables to use in clustering: For this exercise, we will continue to use knnPredV () defined in the notes and listed below for reference (along with knnNat): ## knnMat definition set.seed (1234) y 1) {class - 0.5, 1, 0))}) }
