Plot event-related potential (ERP) waveform

Generates an ERP plot from epoched data.

Usage

plotERP(x, channel = 1L, ci = 0.95, show_epochs = FALSE, epoch_alpha = 0.2)

Arguments

x

An epoched PhysioExperiment object.

channel

Integer index or character name of the channel.

ci

Confidence interval level (0-1). NULL for no CI.

show_epochs

Logical. If TRUE, shows individual epoch traces.

epoch_alpha

Alpha value for individual epoch traces.

Value

A ggplot object.
