[R] ROCR crashes for simple recall plot

I'm trying to use ROCR to create a simple cutoff vs recall plot (recall@p) on the example ROCR.simple dataset: library(ROCR) data(ROCR.simple) pred <- prediction(ROCR.simple$predictions, ROCR.simple$labels) perf <- performance(pred, "rec") plot(perf) But R crashes on me on the last line. I'm usi
