plot_difference: Difference Plots for 9 ROI

In aherbay/erpscope: Visualize ERPs in R

Difference Plots for 9 ROI

Description

This function creates a plot file with 9 electrodes of interests 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_difference(
  data,
  plotname = "auto",
  conditionToPlot = MM_RAW,
  levelA = semMM_RAW,
  levelB = consistent,
  custom_colors = list(c("levelA", "#000000"), c("levelB", "#4DAF4A"), c("difference",
    "#595959"), c("t-test", "#EA2721")),
  output_type = "pdf",
  ant_levels = Anteriority.Levels,
  med_levels = Mediality.Levels,
  vary = Voltage,
  group_var = Subject,
  show_group_obs = FALSE,
  labels_vertical_position = "auto",
  labels_height = "auto",
  baseline = c(-500, -200),
  topoplots_data = "voltage_difference",
  topoplots_time_windows = list(c(-250, -150), c(-150, 50), c(50, 200), c(200, 300),
    c(300, 500), c(500, 700), c(700, 900)),
  topoplots_scale = "auto",
  time_labels_interval = 200,
  custom_labels = list(),
  electrodes_to_display = c(),
  show_t_test = FALSE,
  t_test_threshold = 0.05,
  line_thickness = 0.75,
  background = "grid",
  adjusted_baseline = FALSE
)

Arguments

data	dataframe containing eeg data
plotname	'auto' or custom string for plot title and plot file name
conditionToPlot	column of the dataframe with the condition to plot
levelA	level to be substracted from
levelB	level to substract
custom_colors	list of colors lists
output_type	file type of the output
vary	variable that is used for the y-axis
group_var	group variable, usually Subject
show_group_obs	to show Subject data
labels_vertical_position	'auto' or custom position for the center of the label (in microVolts)
labels_height	'auto' or custom height (in microVolts)
topoplots_time_windows	list defining the time-windows for the voltage maps
topoplots_scale	'auto' or vector defining the limits of the scale for voltage maps
custom_labels	list of custom label list. Each custom labels should have the structure: list(start_time, end_time, "label")
line_thickness	single value (numeric, e.g. 0.75) or a vector of numerics such as: c(0.75, 1 , 1.25, 1.5)
background	string that defines the color of the background : "grid" (default), "white" and "dark"
adjusted_baseline	boolean to indicate if the baseline should be simulated on the time-window provided in
line_type	single value (string, e.g. 'solid') or a vector of strings such as: c('solid', 'dotted , 'dashed','longdash','F1')

Value

A PDF file containing the Difference plots by electrodes or region
