[R] ROCR package partial false positive and accuracy
Hi, In the ROCR package is there a way to find the accuracy that corresponds to a given false positive rate. In version 1.0-2, the authors of the package added an option to find the partial area under the ROC curve up to a given false positive rate by passing an optional parameter fpr.stop: perf.auc<-performance(pred,"auc",fpr.stop=0.15) Is there a way to find the accuracy up to a given false positive rate. We use a classification tree (rpart) and a binary response. Thanks, Saeed --- R 2.8.1 Win XP pro rpart 3.1-43 rocr 1.0-2
