I just realized this is a duplicate
> SparkR NaiveBayes should not require label to have NominalAttribute

> Issue Type: Improvement
> Components: ML, SparkR
> Reporter: Joseph K. Bradley
>
> Currently, SparkR's NaiveBayes API fails if the label is numeric. It works
> if the label is a String. This is because NaiveBayesWrapper requires that
> the input column be annotated with NominalAttribute, which is created when
> Strings are indexed by RFormula. We should eliminate this restriction since
> it causes failures easily, such as when trying to run NB on LibSVM datasets.
