A hyperframe is like a data frame, except that its entries can be objects of any kind. The behaviour of these methods is analogous to the corresponding methods for data frames.
The value returned from
split.hyperframe is a list of
the values for the groups. The components of the list are named
by the levels of

a factor and
drop = TRUE, dropping unused levels).
