erp_scalp: Plot ERPs on the scalp

In kusumikakd/EEG: A collection of utilities for EEG analysis

Description

Creates an ERP figure for each electrode and layouts them on the scalp.

Usage

erp_scalp(
  data,
  electrode = "electrode",
  amplitude = "amplitude",
  time = "time",
  color = NULL,
  size = 0.8,
  baseline = NULL,
  show_guide = TRUE,
  montage = NULL
)

Arguments

data	An EEG dataset.
electrode	Column name containing electrode names in data. Defaults to "electrode".
amplitude	Column name containing amplitudes in data. Defaults to "amplitude".
time	Column name containing time in data. Defaults to "time".
color	Variable to color lines by. If no variable is passed, only one line is drawn for each electrode.
size	Size of line(s).
baseline	Character vector of times to subtract for baseline correct.
show_guide	Should a guide be shown.
montage	Name of an existing montage set. Defaults to NULL; (currently only 'biosemi64alpha' available other than default 10/20 system)

Details

The function uses default electrode names and locations contained in the package.

Value

Returns a ggplot2 plot object.
