I have a question about ROCR package. I got the ROC curve plotted
without any problem following the manual. However, I don't know to
extract the values, e.g. y.values ( I think it is the area under the
curve auc measure). The return is an object of class "performance"
which have Slots and one of the slot is "y.values". I type the object
and I can see them in screen. But I want to extract the value for
further programming and computation. I did a summary of the object
and it is a "S4" mode which I don't understand.
Can someone help?
Thanks a lot in advance.
