-------------------------------------------
I'm doing a general pass to encourage the Shepherd requirement from the roadmap
process in [SPARK-18813].
Is someone interested in shepherding this issue, or shall I remove the target
version?

> R formula drop the first category alphabetically when encode string/category

> into vector, but only supporting "dropLast" by string/category frequencies.
> This will cause SparkR produce different models compared with native R.
