## Data set: Simple artificial prediction data for use with ROCR

### Description

A mock data set containing a simple set of predictions and corresponding class labels.

### Usage

    data(ROCR.simple)

### Format

A two element list. The first element, `ROCR.simple$predictions`, is a vector of numerical predictions. The second element, `ROCR.simple$labels`, is a vector of corresponding class labels.

### Examples

    # plot a ROC curve for a single prediction run
    # and color the curve according to cutoff.
    data(ROCR.simple)
    pred <- prediction(ROCR.simple$predictions, ROCR.simple$labels)
    perf <- performance(pred,"tpr","fpr")
    plot(perf,colorize=TRUE)
