View source: R/rocs.fptp.R

Description

The function plots the colored ROCS in 3 dimensions using the rgl utilities. It shades the FDR-controlled AUC in the FPR-TPR plain. The VUS of the surface and the FCAUC area are calculated.

Usage

1
rocs.fptp(FP, TP, TDR, FDR.cut = 0.2)

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.

Details

The ROCS is the surface spanned by the TPR-FPR-TDR and its projection to the TPR-TDR plain. The vulume is between the surface and its projection on the TPR-FDR plain (i.e. the AUC of ROC).

Value

The volume under the surface (VUS) is returned.
