plot_sscaROC {caROC}

Plot covariate-adjusted ROC for specific subpopulations.

Description

Function to plot the ROC curve generated from sscaROC().

Usage

plot_sscaROC(myROC, ...)

Arguments

myROC

ROC output from sscaROC() function.

...

Arguments to tune generated plots.

Details

This function can be used to plot other ROC curve, as long as the input contains two components "sensitivity" and "specificity".

Value

Plot the ROC curve.
