Hi all, 

I would like to calculate the area under the ROC curve for my predictive
model. I have managed to plot points giving me the ROC curve. However, I do
not know how to get the value of the area under. 
Does anybody know of a function that would give the result I want using an
array of specificity and an array of sensitivity as input?
