how to create ROC curve for 2 dimensional classifiers
I'm not aware of any packages for doing such plots. Conceptually, presumably a ROC curve for a 2d classifier would be a 3d chart, with x-axis being FPR for 1st classifier, z-axis being FPR for 2nd classifier and y-axis being TPR. You would get a "ROC surface" rather than a ROC curve. Does that make sense? Regards Richard.

Hi, I understand for 1 d classifiers, you can use ROCR package. Is there a package you can plot ROC curve for 2d classifiers? One of my colleagues asked me about this. I have been quite puzzled, conceptually, how you can do the ROC curve for 2d classifiers. Can someone share his/her knowledge or experience? Thanks in advance.
