compareROC: Make ROC plots.

In gprege: Gaussian Process Ranking and Estimation of Gene Expression time-series

Description

This rocStats wrapper superimposes ROC curves on a plot to analyse the output performance of a method-A, and optionally compare it with that of a method-B, based on some ground thruth labels.

Usage

  compareROC(output, groundTruthLabels, compareToRanking)

Arguments

output	(vector) The output of ranking scores returned by method-A for each data-point.
groundTruthLabels	(vector) A binary vector that contains the ground truth (e.g. which genes are members of the top-100 ground truth list).
compareToRanking	A matrix where each column is the output vector of ranking scores returned by another competing method.

Value

area	A scalar. The area under the ROC curve of method-A.
