Hi everybody,

I have a data set with a value and a status (positive or negative case) and
I want make a ROC Analysis. So, with ROCR Package, I have got the ROC curve
(True Positive Fraction [tpf] according 1-True Negative Fraction [1-tnf]).


But, now I want a new graphic which show the sum of true positive fraction
and true negative fraction according each value on my data set (tpf + tnf
according the values). 


If you have an idea !

Thank you very much for all help,
Camille Leclerc
