ROC curve for each fold in one plot
...Then I need ROC curve for each fold:
> set.seed(1)
> train_control <- trainControl(method="cv", number=5,savePredictions = TRUE,classProbs = TRUE)
> output <- train(Species~., data=iris, trControl=train_control, method="rf")
> library(pROC)
> selectedIndices <- output$pred$Resample == "Fold1"
> plot.roc(output$pred$obs[selectedIndices],output$pred$setosa[selectedIndices]) > selectedIndices <- output$pred$Resample == "Fold2"
> plot.roc(output$pred$obs[selectedIndices],output$pred$setosa[selectedIndices])
>...
