Given the predicted value q and the observed classes y,
it shows an overview of the prediction performances with hit rates,
misclassification rates, true positives (TP), false positives (FP)
and precision.
classification(q, y, classes = c("-1", "1"), weights = NULL)a list with three elements, matrix equals the confusion
matrix,overall equals the overall prediction performance and
in measures the measures per class is stored.
the predicted values
a list of the actual classes of q
a character vector with the labels of the two classes
an optional parameter to specify a weighted hit rate and misclassification rate
