Standardise SCR or SCL using within-participant range correction — standardise_gazepoint_range

Adds a range-corrected signal column using (x - min) / (max - min) within participant or another grouping unit. This expresses each value as a proportion of the observed within-unit range.

Usage

standardise_gazepoint_range_correction(
  dat,
  signal_col,
  group_col = "source_participant",
  suffix = "_Range_Corrected",
  min_valid = 2,
  zero_range_action = c("NA", "zero"),
  overwrite = FALSE
)

standardize_gazepoint_range_correction(
  dat,
  signal_col,
  group_col = "source_participant",
  suffix = "_Range_Corrected",
  min_valid = 2,
  zero_range_action = c("NA", "zero"),
  overwrite = FALSE
)

Arguments

dat: A data frame containing SCR, SCL, or another biometric signal.
signal_col: Signal column to range-correct.
group_col: Participant or unit column.
suffix: Suffix for the output column.
min_valid: Minimum finite observations required within each group.
zero_range_action: What to do when max equals min: "NA" or "zero".
overwrite: Logical. If FALSE, existing output columns are protected.

Value

A data frame with an added range-corrected column.
