R Documentation

Generating ROC plot with shading based on FDR using user-provided FPR, TPR, FDR values

Description

The function plots the ROC curve using user-provided FPR, TPR, FDR values. It shades the area corresponding to acceptable FDR level. The FDR-controlled area under the curve (FCAUC) is calculated for the shaded area.

Usage

fcauc.fptp(FP, TP, TDR, FDR.cut = 0.2, do.plot=TRUE)

Arguments

`FP`	Vector of false positive rate.
`TP`	Vector of true positive rate.
`TDR`	Vector of true discovery rate.
`FDR.cut`	The cutoff value of FDR, for the purpose of FCAUC cualculation.
`do.plot`	Whether to generate the plot.

Value

The FCAUC value is returned.
