Plot 1-D timecourse data.

Typically event-related potentials/fields, but could also be timecourses from frequency analyses for single frequencies. Averages over all submitted electrodes. Output is a ggplot2 object.

Arguments

data

EEG dataset. Should have multiple timepoints.

...

Other arguments passed to methods.

electrode

Electrode(s) to plot.

time_lim

Character vector. Numbers in whatever time unit is used specifying beginning and end of time-range to plot. e.g. c(-.1, .3)

add_CI

Add confidence intervals to the graph. Defaults to 95 percent between-subject CIs.

baseline

Character vector. Times to use as a baseline. Takes the mean over the specified period and subtracts. e.g. c(-.1,0)

colour

Variable to colour lines by. If no variable is passed, only one line is drawn.

color

Alias for colour.

mapping

A ggplot2 aes() mapping.

component

name or number of ICA component to plot

freq_range

Choose a specific frequency range to plot

type

Type of baseline correction to use for eeg_tfr objects

Value

Returns a ggplot2 plot object
