target:  Returns an enumeration describing the available options Valid options are: <p> -F number <br> The number of folds for reduced error pruning. One fold is used as the pruning set. (Default: 3) <p> -N number <br> The minimal weights of instances within a split. (Default: 2) <p> -O number <br> Set the number of runs of optimizations. (Default: 2) <p> -D <br> Whether turn on the debug mode -S number <br> The seed of randomization used in Ripper.(Default: 1) <p> -E <br> Whether NOT check the error rate >= 0.5 in stopping criteria. (default: check) <p> -P <br> Whether NOT use pruning. (default: use pruning) <p>
