In tjmahr/fillgaze: Interpolate Missing Eyetracking Data

Description

Fill in gaps of missing eyetracking data

Usage

fill_gaze_gaps(data, ..., time_var = NULL, max_na_rows = NULL,
  max_duration = NULL, max_sd = NULL)

Arguments

data	a dataframe of eyetracking data
...	columns to interpolate selected using dplyr selection semantics
time_var	(optional) the name of a column in data containing the timestamps of eyetracking samples. Defaults to using row numbers.
max_na_rows	(optional) do not fill in gaps larger than max_na_rows rows
max_duration	(optional) do not fill in gaps longer than max_na_rows in duration
max_sd	(optional/experimental) do not fill in gaps where the change from pre-missing to post-missing is more than max_sd * z, where z is the standard deviation of frame-to-frame changes in values in that column.
