Flag device-limit counts within time windows

Groups samples into fixed-duration windows from the first timestamp, counts values at the positive and negative device limits on each axis, and compares each count with min_count.

Usage

acti_flag_device_limit_windows(
  data,
  dynamic_range = NULL,
  epsilon = 0.05,
  min_count = 1,
  window_seconds = 60
)

Arguments

data

Raw accelerometer samples with a timestamp column.

dynamic_range

Device range; inferred when omitted.

epsilon

Margin inside the device limit, in g.

min_count

Minimum number of samples required within a window.

window_seconds

Window duration in seconds.

Value

One row per window with axis-specific flags.
