I'm checking several tests for a disease condition. When a criterion in a
test is ">" for disease, R gave me the same curve as I got from Origin. When
the criterion is "<" for disease, the peak of the curve is opposite to the
one Origin created, that means the AUC < 0.5. The Origin curve is correct,
which fits my se and sp data. The pROC manual told me to use the direction
function but it didn't work - it said that direction is not recognized. Can'
t figure out what's wrong. Can anyone help me? Thanks!
