plot_roc_overlay {EGAD} | R Documentation

## 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

`scores.mat` | numeric array
`labels.mat` | numeric array
`nbins` | numeric value

### 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)
