Method: OpenTox::Dataset#split

Defined in:
lib/dataset.rb

#split(compounds, features, metadata, subjectid = nil) ⇒ OpenTox::Dataset

Creates a new dataset, by splitting the current dataset, i.e. using only a subset of compounds and features

Parameters:

  • compounds (Array) —

    List of compound URIs

  • features (Array) —

    List of feature URIs

  • metadata (Hash) —

    Hash containing the metadata for the new dataset

  • subjectid (String) (defaults to: nil)

Returns:
