ROC curves in the upper part of the figure the ROC curve of the merged from www.researchgate.net Using of the roc.plot () function. I particularly like the way the performance() function has you set up calculation of the curve by entering the true positive rate, tpr, and false positive rate, fpr, parameters.not only is this reassuringly transparent, it shows the flexibility to calculate nearly. This enables computation of inference procedures:
