Description

Accessor and replacement functions for the roc slot in a COBRAPerformance or COBRAPlot object.

Usage

roc(x, ...)

roc(x, ...) <- value

## S4 method for signature 'COBRAPerformance'
roc(x)

## S4 replacement method for signature 'COBRAPerformance,data.frame'
roc(x) <- value

## S4 replacement method for signature 'COBRAPlot,data.frame'
roc(x) <- value

Arguments

x	A COBRAPerformance or COBRAPlot object.
...	Additional arguments.
value	A data frame giving information necessary to generate ROC curves for each method and each stratification level.

Value
