class NullToNaNVectorAssembler extends Transformer with HasInputCols with HasOutputCol with HasColumnAttributeMap with DefaultParamsWritable

:: Experimental :: A feature transformer that merges multiple columns into a vector column.

This class is a copy of VectorAssembler with two enhancements: support for nulls (replaced to NaNs) and pattern matching extracted from the inner loop.
