Audit likely GSR/EDA units — audit_gazepoint_gsr

Checks whether a Gazepoint GSR/EDA column looks more like conductance in microSiemens or resistance/impedance-like values in Ohms. This is a preprocessing safety audit, not a definitive device calibration test.

Usage

audit_gazepoint_gsr_units(
  dat,
  gsr_col = "GSR",
  convert = FALSE,
  output_col = NULL,
  resistance_to_us_factor = 1e+06
)

Arguments

dat: A data frame.
gsr_col: Name of the GSR/EDA column to audit.
convert: Logical. If TRUE, add a conductance-converted column when the signal is likely resistance/impedance-like.
output_col: Output column used when convert = TRUE.
resistance_to_us_factor: Conversion factor. For Ohms to microSiemens, use 1000000 / resistance.

Value

A list with overview, diagnostics, recommendation, and, when requested, data.
