ERP Difference Waveform — eegERPdifference • PhysioEEG

Computes the difference waveform between two PhysioExperiment objects by subtracting the assay data of y from x.

Usage

eegERPdifference(x, y, assay_name = NULL, output_assay = "difference")

Arguments

x: A PhysioExperiment object (minuend).
y: A PhysioExperiment object (subtrahend). Must have the same dimensions as x.
assay_name: Input assay name (default: first assay).
output_assay: Output assay name (default: "difference").

Value

Modified x with difference waveform stored in output_assay. The difference assay has the same dimensions as the input assay.
