  data,
  pupil_cols = NULL,
  time_col = NULL,
  blink_col = NULL,
  max_gap_s = NULL,
  method = c("linear", "constant"),
  suffix = "_interp"
)

Arguments

data: Data frame containing pupil columns.
pupil_cols: Pupil columns to interpolate. If omitted, common pupil columns are detected.
time_col: Optional time column.
blink_col: Optional logical/numeric blink mask column.
max_gap_s: Optional maximum interpolated gap duration in seconds.
method: Interpolation method passed to stats::approx().
suffix: Suffix for interpolated pupil columns.

Value

Data frame with interpolated pupil columns and audit flags.
