?ci.se?            Compute the CI of sensitivities at given specificities      
       ?ci.sp?            Compute the CI of specificities at given sensitivities      
       ?ci.thresholds?    Compute the CI of specificity and sensitivity of thresholds
       ?ci.coords?        Compute the CI of arbitrary coordinates

# Alternatively, you can get the CI directly from roc():
     rocobj <- roc(aSAH$outcome,
                   aSAH$s100b, ci=TRUE, of="se", boot.n=100)
     rocobj$ci
    
     # Plotting the CI
     plot(rocobj)
     plot(rocobj$ci)
