Interpolate missing pupil samples — interpolate • eyeris

Linear interpolation of time series data. The intended use of this method is for filling in missing pupil samples (NAs) in the time series. This method uses "na.approx()" function from the zoo package, which implements linear interpolation using the "approx()" function from the stats package. Currently, NAs at the beginning and the end of the data are replaced with values on either end, respectively, using the "rule = 2" argument in the approx() function.

Usage

interpolate(eyeris)

Arguments

eyeris: An object of class eyeris dervived from load().

Value

An eyeris object with a new column in timeseries: pupil_raw_{...}_interpolate.

Examples

system.file("extdata", "memory.asc", package = "eyeris") |>
  eyeris::load_asc() |>
  eyeris::deblink(extend = 50) |>
  eyeris::detransient() |>
  eyeris::interpolate() |>
  plot(seed = 0)
