How to find AUC in SVM (kernlab package)
...imamodel
fitted(pimamodel)
pima.pred <- predict(pimamodel, Pima.te[,-8], type="probabilities")
pima.pred
# try to find AUC
#predid.no <- prediction(pima.pred[,1], Pima.te[,8])
#predid.yes <- prediction(pima.pred[,2], Pima.te[,8])
predid <- prediction(pima.pred, Pima.te[,8])
perfid <- performance(predid,"tpr","fpr")
perfid.auc <- performance(predid,"auc")
perfid.auc
Thank you very much for your help.
