actisomni 0.4.0

• acti_sleep_hdcza(), acti_sleep_horangle(), acti_sleep_sib(), and acti_sleep_ensemble() gain a smooth argument. The default, "rollmedian", takes a five-second rolling median of each raw axis before computing the angle, as described by van Hees et al. (2015, 2018) and implemented in GGIR’s anglez. This changes results: earlier versions computed the angle from each raw sample, which smooth = "none" restores. Smoothing warns when the timestamps have gaps, because the median window is counted in samples.
• acti_sleep_ensemble() smooths the raw axes once and reuses them for every angle-based guider, so messages and warnings are no longer repeated.
• Requires asleep (>= 0.4.0).

actisomni 0.3.0

• acti_asleep() and py_acti_asleep() now return times in the input’s time zone. asleep reports local clock times without a time zone, which were previously labelled UTC, shifting predictions by the UTC offset of the input (e.g. one hour for British Summer Time). A new tz argument sets the time zone, which is needed for file-path input (default "UTC").
• For data-frame input, acti_asleep() and py_acti_asleep() pass asleep a clock held at the UTC offset at the start of the recording, so the clock never repeats or skips an hour at a daylight-saving transition and the returned times are the exact input instants. File input still reads the device clock in tz, so the two can differ after a transition.
• acti_sleep_hdcza() now defaults to GGIR’s data-driven threshold: 15 times the 10th percentile of the five-minute rolling median absolute angle change, limited to 0.13–0.5 degrees. The percentile and multiplier are set with the new threshold_percentile and threshold_multiplier arguments (GGIR’s HDCZA_threshold = c(10, 15)). threshold now defaults to NULL; set it to a number for a fixed threshold, e.g. threshold = 0.2 for the previous default.
• The HDCZA rolling statistic is now the median absolute angle change within each five-minute window of angles, as in GGIR, rather than the median of the changes over a window one epoch wider.
• epoch arguments (guiders, acti_sleep_sib(), acti_sleep_ensemble(), acti_sleeper()) accept numeric seconds or strings such as "30 seconds", standardized with actibase::acti_standardize_epoch().
• Requires actibase (>= 0.8.0) for acti_standardize_epoch().

actisomni 0.2.0

• Removed the Tudor–Locke sleep-period adapter and diary-labeling helper; these are now provided through actimetrics.
• Removed actigraph.sleepr from Imports; actisomni no longer calls it.
• Trying to cleanup uv lock.
• Upgraded R version for pipe.

actisomni 0.1.0

• Initial creation.
