How to plot a ROC curve?

Hello,
I would appreciate a lot any help for understanding how can i compute required parameters for plotting ROC curve? Particularly, i found that it could be done by perfcurve function but i dont understand how to derive required inputs (labels, scores and posclass) from my input matrix.
Thank you in advance for any help
