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

Examples

set.seed(123)
R1 <- rocdemo.sca( rbinom(40,1,.3), rnorm(40), dxrule.sca,
   caseLabel="new case", markerLabel="demo Marker" )
plot( R1, show.thresh=TRUE )
