Audit Gazepoint GSR/EDA signal quality — audit_gazepoint_gsr

Audits Gazepoint GSR/EDA columns for missingness, inactive zero rows, validity flags, plausible value ranges, flatlining, and usable sample coverage. When available, GSR_US is used by default because it represents skin conductance in microsiemens in Gazepoint exports.

Usage

audit_gazepoint_gsr_quality(
  data,
  value_column = NULL,
  validity_column = "GSRV",
  min_value = 0,
  max_value = 100,
  jump_threshold = NULL
)

Arguments

data: A data frame or a path to a Gazepoint CSV export.
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".
min_value: Minimum plausible value.
max_value: Maximum plausible value.
jump_threshold: Optional threshold for detecting large sample-to-sample jumps.

Value

A one-row data frame summarising signal quality.
