Decided to start githib with ROC curve plotting example. There is not a one ROC curve but several – according to the number of comparisons (classifications), also legend with maximal and minimal ROC AUC are added to the plot. ROC curves and ROC AUC were calculated with ROCR package.

What else should be added to the plot for ease of understanding?
