detect_blinks_by_size: detect blinks by a change in pupil size

In samhforbes/PupillometryR: A Unified Pipeline for Pupillometry Data

detect blinks by a change in pupil size

Description

This allows the user to set a threshold for pupil size and remove anything classed as a blink as a result

Usage

detect_blinks_by_size(
  data,
  pupil,
  threshold = 2.5,
  extend_forward = 0,
  extend_back = 0
)

Arguments

data	dataset of class PupillometryR
pupil	column name for pupil data
threshold	velocity threshold for blink detection
extend_forward	number of observations to remove forward of blink
extend_back	number of obervations to remove behind blink

Value

returns dataframe with blinks removed including forward and back, and data in blink column.

Examples

Sdata <- make_pupillometryr_data(data = pupil_data,
subject = ID,
trial = Trial,
time = Time,
condition = Type)

Sdata2 <- detect_blinks_by_size(data = Sdata,
pupil = LPupil,
threshold = 2.5,
extend_forward = 0,
extend_back = 0)
