plot_coord: Visualization of significant differences in ERPs using...

In PsyChiLin/ERPplot: Graphical exploration of ERP data

Description

The plot coord takes the results of plot_fa to create a animated GIF plot for visualizing significant differences in ERPs across locations on the scalp over time.

Usage

plot_coord(tests_rst, frames, show, point_size = 14, high_col = "firebrick",
  low_col = "forestgreen", na_col = "grey70", text = T, text_size = 3,
  text_col = "black", circle = T, nose = T, cir_nose_col = "black",
  loop = 1, ...)

Arguments

tests_rst	the testing result from plot_fa.
frames	The time point of the ERP data
show	Which frames to show in the animation.
point_size	The size of the points (channels) on the scalp.
high_col	The color for "highly" significant time point (smaller p value).
low_col	The color for "low or no significant" time point (bigger p value).
na_col	The color for no specified channels on full 10-10 system.
text	Logical variable. Whether to show the channel label or not.
text_size	The text size of the channel label (when text = TRUE).
text_col	The text color of the channel label (when text = TRUE).
circle	Logical variable. Whether to show the scalp circle or not.
nose	Logical variable. Whether to show the nose or not.
cir_nose_col	The color of the nose (when nose = TRUE).
loop	The parameter for adjusting animations in ani.options. Whether to iterate or not (default TRUE to iterate for infinite times)
...	Further parameters in ani.options to adjust the animation (i.e. interval = 0.5), and gg_animate to save the animation.
