Flag outlying Gazepoint RR/IBI intervals — flag_gazepoint_rr_outliers • gpbiometrics

Flags implausible RR intervals using absolute physiological limits and either robust MAD-based or z-score-based deviation rules.

Usage

flag_gazepoint_rr_outliers(
  rr_intervals,
  method = c("mad", "z", "range"),
  z_threshold = 5,
  mad_threshold = 5,
  min_rr = 300,
  max_rr = 2000,
  return = c("flags", "filtered", "data")
)

Arguments

rr_intervals: Numeric RR/IBI vector, usually in milliseconds.
method: "mad", "z", or "range".
z_threshold: Z-score threshold when method = "z".
mad_threshold: Robust MAD threshold when method = "mad".
min_rr: Minimum plausible RR interval in ms.
max_rr: Maximum plausible RR interval in ms.
return: "flags", "filtered", or "data".

Value

Logical vector, filtered RR vector with outliers set to NA, or a data frame with reason columns.

Examples

flag_gazepoint_rr_outliers(c(800, 810, 3000, 790))
