- Add
rowwise_dt()
to createdata.table
object rowwisely. Note that this function has been filed todata.table
in PR#4291 (not merged yet), with the function namerowwiseDT()
. - Add a set of assertive functions (e.g.,
assert_pk()
). time_taken()
is a wrapper version ofdata.table::timetaken()
, which is useful for me to use interactively.
