Easy way of counting precision, recall and F1-score in R

Question

I am using an rpart classifier in R. The question is - I would want to test the trained classifier on a test data. This is fine - I can use the predict.rpart<

Answer 1

confusionMatrix() from caret package can be used along with a proper optional field "Positive" specifying which factor should be taken as positive factor.

confusionMatrix(predicted, Funded, mode = "prec_recall", positive="1")

This code will also give additional values such as F-statistic, Accuracy, etc.
