.. py:function:: ak.from_rdataframe(rdf, columns)


    :param rdf: ROOT RDataFrame to convert into an
            Awkward Array.
    :type rdf: ``ROOT.RDataFrame``
    :param columns: A column or multiple columns to be
                converted to Awkward Array.
    :type columns: str or iterable of str

Converts ROOT RDataFrame columns into an Awkward Array.

If ``columns`` is a string, the return value represents a single RDataFrame column.

If ``columns`` is any other iterable, the return value is a record array, in which
each field corresponds to an RDataFrame column. In particular, if the ``columns``
iterable contains only one string, it is still a record array, which has only
one field.
