Daru::DataFrame#rename_vectors

Renames the vectors

== Arguments

* name_map - A hash where the keys are the exising vector names and
             the values are the new names.  If a vector is renamed
             to a vector name that is already in use, the existing
             one is overwritten.

== Usage

  df = Daru::DataFrame.new({ a: [1,2,3,4], b: [:a,:b,:c,:d], c: [11,22,33,44] })
  df.rename_vectors :a => :alpha, :c => :gamma
  df.vectors.to_a #=> [:alpha, :b, :gamma]
