renamed to overlaps()
. overlap()

another convenience overlap_method
for NO kind of overlap +
expand_number_line()
- new options for point
; "left"
and "right"
+ compress_number_line()
- compressed number_line
object inherits
the direction of the widest number_line
among overlapping group of
number_line
objects + overlap_methods
- have been changed such that
each pair of number_line
objects can only overlap in one way. E.g. +
"chain"
and "aligns_end"
used to be possible but this is now
considered a "chain"
overlap only + "aligns_start"
and
"aligns_end"
use to be possible but this is now considered an
"exact"
overlap + number_line_sequence()
- Output is now a list
. +
number_line_sequence()
- now works across multiple number_line
objects. + to_df()
- can now change number_line
objects to
data.frames. + to_s4()
can do the reverse. + epid
objects are the
default outputs for fixed_episodes()
, rolling_episodes()
and
episode_group()
+ pid
objects are the default outputs for
record_group()
+ In episode grouping, the case_nm
for events that
were skipped due to rolls_max
or episodes_max
is now "Skipped"
. +
In episode_group()
and record_group()
, sn
can be negative numbers
but must still be unique + Optimised episode_group()
and
record_group()
. Runs just a little bit faster … + Relaxed the
requirement for x
and y
to have the same lengths in overlap
functions. + The behaviour of overlap functions will now be the same as
that of standard R logical tests + episode_group
- case_length
and
recurrence_length
arguments. Now accepts negative numbers. + negative
“lengths” will collapse two periods into one, if the second one is
within some days before the end_point()
of the first period. + if the
“lengths” are larger than the number_line_width()
, both will be
collapsed if the second one is within some days (or any other
episode_unit
) before the start_point()

no duplicates. Resolved + case_nm
wasn’t right for rolling episodes.
