Standardise SCR or SCL using intra-individual z-scoring — standardise_gazepoint

Adds a within-participant z-scored version of a signal column. This is a lightweight compatibility wrapper around the package's more general within-unit standardisation helper.

Usage

standardise_gazepoint_zscore(
  dat,
  signal_col = "SCR_Amplitude",
  group_col = "source_participant",
  suffix = "_Z",
  min_valid = 2,
  overwrite = FALSE
)

standardize_gazepoint_zscore(
  dat,
  signal_col = "SCR_Amplitude",
  group_col = "source_participant",
  suffix = "_Z",
  min_valid = 2,
  overwrite = FALSE
)

Arguments

dat: A data frame containing SCR, SCL, or another biometric signal.
signal_col: Signal column to standardise.
group_col: Participant or unit column.
suffix: Suffix for the output column.
min_valid: Minimum finite observations required within each group.
overwrite: Logical. If FALSE, existing output columns are protected.

Value

A data frame with an added z-scored column.
