plotERParray: Plot ERP curves

In tdeenes/eegR: Analyze EEG Signals

Description

plotERParray is a generalization of matplot onto array inputs.

Usage

plotERParray(
  dat,
  xdim = "time",
  sepdim = "chan",
  gfp_plot = if (sepdim == "chan") TRUE else FALSE,
  gfp_col = "black",
  gfp_lwd = 1.3,
  minus_up = if (gfp_plot) FALSE else TRUE,
  title = "",
  subtitle_col = "black",
  xlab = xdim,
  ylab = "amplitude",
  grid_dim = NULL,
  ...
)

Arguments

dat	a numeric array with named dimensions
xdim	character string; the name of the dimension of dat which defines the x axis (default: "time")
sepdim	character string; the name of the dimension of dat which separates the lines (default: "chan")
gfp_plot	logical value whether GFP curves should be also plotted (only if 'sepdim' is "chan")
gfp_col	the colour of the GFP curves (if plotted)
gfp_lwd	the thickness of the GFP curves (if plotted)
minus_up	logical value; if set to TRUE, minus values are plotted upwards. If FALSE, minus values are plotted downwards. By default, it is set to TRUE or FALSE depending on the 'gfp_plot' argument.
title	character string; the title of the plot
subtitle_col	colour(s) of the subtitles (recycled if necessary)
xlab	character string; the title of the x axis (defaults to the 'xdim' argument)
ylab	character string; the title of the y axis (default: "amplitude")
grid_dim	integer vector giving the number of rows and columns in which the plots are arranged; if set to NULL (default), the arrangement of the plot is set up automatically
...	additional parameters to be passed to matlines

Examples

# example data
data(erps)

# compute grand averages
plotdat <- avgDims(erps, "id")

# plot the channels in light grey, draw only solid lines
plotERParray(plotdat, col = "grey70", lty = 1)
