rnalysis.filtering.FoldChangeFilter.union

FoldChangeFilter.union(*others: Filter | set, return_type: Literal['set', 'str'] = 'set')

Returns a set/string of the union of features between multiple Filter objects/sets (the features that exist in at least one of the Filter objects/sets).

Parameters:

  • others (Filter or set objects.) – Objects to calculate union with.

  • return_type ('set' or 'str' (default='set')) – If β€˜set’, returns a set of the union features. If β€˜str’, returns a string of the union WBGene indices, delimited by a comma.

Return type:

set or str

Returns:

a set/string of the WBGene indices that exist in at least one of the Filter objects.

Examples:
>>> from rnalysis import filtering
>>> d = filtering.Filter("tests/test_files/test_deseq.csv")
>>> counts = filtering.Filter('tests/test_files/counted.csv')
>>> # calculate union and return a set
>>> d.union(counts)
