Arguments
- thresh
speed_clean Threshold (z point or absolute value) above which values are marked as NA.
- speed_method
speed_clean Whether the 'thresh' is a z-score ('z'), with deviant values omitted once, or until there are no more values above the threshold ('z-dynamic'). 'abs' is used instead when a precise absolute value for speed is supplied.
- extend_by
speed_clean Number of samples starting from the deviant speed values that are stripped (e.g., the signal in proximity of blinks may be biased as well).
- island_size
speed_clean Islands of signal in the midst of NAs are removed if smaller or equal to this threshold (amount of samples).
- extend_blink
interpolate NAs are extended by these many samples prior to interpolation. This gets rid of signal that may be compromised in the close proximity of a blink.
- overall_thresh
interpolate Overall quality threshold: e.g., the total amount of data that is allowed to be missing from the original vector.
- consecutive_thresh
interpolate Consecutive gaps in the signal: e.g., the total amount of data that is allowed to be missing from the original vector consecutively.
- disable_smoothing
smooth Whether you want to disable smoothing. This parameter is FALSE by default; if you want to disable the smoothing, set it to TRUE.
- spar
smooth Smoothing factor as in 'smooth.spline()'.
