## 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.
