The confusion matrix shows how many times a pattern
with the real class x was classified as class y. A perfect method
should result in a diagonal matrix. All values not on the diagonal
are errors of the method.
Usage
confusionMatrix(targets, predictions)
Arguments
targets
the known, correct target values
predictions
the corresponding predictions of a method for the targets
Value
the confusion matrix
Details
If the class labels are not already encoded, they are encoded using encodeClassLabels
(with default values).
