In eyeprocess: Harmonize Eye-Tracking, Pupillometry, Biometrics, and Psychometric Process Data

Coordinate semantic-fidelity audit

Description

Detects lossless preservation and stable affine coordinate transformations.

Usage

coordinate_fidelity_audit(
  source,
  roundtrip,
  source_x = "x",
  source_y = "y",
  roundtrip_x = source_x,
  roundtrip_y = source_y,
  key = NULL,
  tolerance = 1e-06,
  correlation_floor = 0.999
)

Arguments

source	Original/source representation.
roundtrip	Round-tripped or comparison representation.
source_x	Source horizontal coordinate column.
source_y	Source vertical coordinate column.
roundtrip_x	Round-tripped horizontal coordinate column.
roundtrip_y	Round-tripped vertical coordinate column.
key	Column or columns used to align records.
tolerance	Numerical tolerance used by the comparison.
correlation_floor	Minimum correlation treated as compatible.

Value

An object of class "eye_coordinate_fidelity", stored as a named list, with components "status", "x", "y", "matched_n", "tolerance", "correlation_floor". It contains coordinate semantic-fidelity audit and associated metadata or diagnostics needed to interpret the result.
