Plot ROC overlay

Description

The function plots a density overlay of ROCs given the scores and labels

Usage

plot_roc_overlay(scores.mat, labels.mat, nbins = 100)

Arguments

Value

list of Z(matrix) and roc_sum (average ROC curve)

Examples

genes.labels <- matrix( c(rep(1, 1000), rep(0,9000)), nrow=1000, byrow=TRUE)
rownames(genes.labels) = paste('gene', 1:1000, sep='')
colnames(genes.labels) = paste('function', 1:10, sep='')

scores <- matrix( rnorm(10000), nrow=1000)
scores <- apply(scores, 2, rank) 
rownames(scores) = paste('gene', 1:1000, sep='')
colnames(scores) = paste('function', 1:10, sep='')

z <- plot_roc_overlay(scores, genes.labels)
