Baseline-correct Gazepoint GSR/EDA — baseline_correct_gazepoint

Adds a baseline-corrected GSR/EDA column to a Gazepoint Biometrics table. When available, GSR_US is used by default because it represents skin conductance in microsiemens in Gazepoint exports. The baseline is estimated from rows selected by baseline_rows, optionally within groups.

Usage

baseline_correct_gazepoint_gsr(
  data,
  baseline_rows,
  value_column = NULL,
  validity_column = "GSRV",
  group_columns = NULL,
  output_column = NULL,
  summary = c("mean", "median"),
  exclude_zero = TRUE
)

Arguments

data: A data frame or a path to a Gazepoint CSV export.
baseline_rows: Logical vector identifying baseline rows.
value_column: Optional GSR/EDA value column. If NULL, GSR_US is used when present, otherwise GSR.
validity_column: Optional validity column. Defaults to "GSRV".
group_columns: Optional grouping columns. When supplied, baselines are estimated separately within each group.
output_column: Name of the corrected output column.
summary: Baseline summary, either "mean" or "median".
exclude_zero: Should zero values be excluded from baseline estimation?

Value

A data frame with the added baseline-corrected column and a baseline-summary attribute named "baseline_summary".
