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

data(ROCR.simple)

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.
