plot_erp: Plot ERP for 9/12 electrodes of interest

In aherbay/erpscope: Visualize ERPs in R

Plot ERP for 9/12 electrodes of interest

Description

This function creates a plot file with 9 or 12 electrodes of interests (for now) displaying ERPs for different conditions. It will need a loaded dataframe with your EEG data and a column indicating the condition to display. It assumes that there is a column named Voltage with your voltage values. Default values are provided for electrodes but it can be customized.

Usage

plot_erp(
  data,
  conditionToPlot,
  electrodes_list = c("F3", "Fz", "F4", "C3", "Cz", "C4", "P3", "Pz", "P4"),
  baseline = c(-2450, -2250),
  color_palette = c("#4DAF4A", "#EA2721", "#377EB8", "#FF7F00", "#984EA3", "#000000",
    "#5c5c5c", "#945D25", "#FF748C", "#2E692C"),
  output_type = "pdf",
  adjusted_baseline = FALSE,
  time_labels_interval = "auto",
  plotname = "auto",
  show_check_message = FALSE,
  show_conf_interval = FALSE,
  custom_labels = list(),
  labels_vertical_position = "auto",
  labels_height = "auto",
  vary = "Voltage",
  background = "grid",
  line_thickness = 0.75,
  line_type = "solid",
  polarity_up = "negative"
)

Arguments

data	dataframe containing ERP data
conditionToPlot	column of the dataframe with different levels to plot
electrodes_list	vector of Electrodes names to plot (between quotes)
baseline	vector defining the baseline used during preprocessing
color_palette	vector with colors for each levels (in the order of levels of conditionToPlot)
output_type	file type of the output
adjusted_baseline	boolean to indicate if the baseline should be simulated on the time-window provided in
plotname	'auto' or custom string for plot title and plot file name
show_check_message	boolean to indicate if you want a confirmation message to be displayed before running the function
show_conf_interval	boolean to indicate if 95% CI (bootstrapped) should be displayed
custom_labels	list of custom label list. Each custom labels should have the structure: list(start_time, end_time, "label")
labels_vertical_position	'auto' or custom position for the center of the label (in microVolts)
labels_height	'auto' or custom height (in microVolts)
vary	variable that is used for the y-axis
background	string that defines the color of the background : "grid" (default), "white" and "dark"
line_thickness	single value (numeric, e.g. 0.75) or a vector of numerics such as: c(0.75, 1 , 1.25, 1.5)
line_type	single value (string, e.g. 'solid') or a vector of strings such as: c('solid', 'dotted , 'dashed','longdash','F1')
polarity_up	defines which polarity is plotted up : "negative" or "positive"

Value

A file containing the ERP plots
