- def apply(xs: Array[String], skip: Int): VectorD
Create a
VectorDfrom an array of Strings, skipping the first 'skip' elements.Create a
VectorDfrom an array of Strings, skipping the first 'skip' elements. If an element is non-numeric, use its hashcode. FIX: Might be better to map non-numeric Strings to ordinal values.- xs
the array of the Strings
- skip
the number of elements at the beginning to skip (e.g., id column)
- def apply(xs: Array[String]): VectorD
Create a
VectorDfrom an array of Strings.Create a
VectorDfrom an array of Strings. For numeric types, assign missing value indicator upon format failure.- xs
the array of the Strings

VectorDfrom one or more values (repeated values String*). For numeric types, assign missing value indicator upon format failure.- x
the first String
- xs
the rest of the Strings
