object representing ROC curve, typically created using rocdemo.sca
Creating Objects
new('rocc', sens = ...., # Object of class numeric spec = ...., # Object of class numeric rule = ...., # Object of class function cuts = ...., # Object of class numeric markerLabel = ...., # Object of class character caseLabel = ...., # Object of class character )
Slots
sens:
Object of class "numeric" sensitivity values
spec:
Object of class "numeric" specificity values
rule:
Object of class "function" rule to classify objects
cuts:
Object of class "numeric" thresholds defining curve
markerLabel:
Object of class "character" name of measured marker
caseLabel:
Object of class "character" name of condition
Methods
plot
(rocc, missing): a plotting function with some additional parameters
