emptyPlot: Utility function

Description

Generate an empty plot window.

Usage

emptyPlot(xlim, ylim, main = NULL, xlab = NULL, ylab = NULL, h0 = NULL,
  v0 = NULL, bty = "n", eegAxis = FALSE, ...)

Arguments

xlim

A one- or two-value vector indicating the range of the x-axis. If xlim is a number, then it is assumed that the other value is 0. Thus, xlim=3000 wil result in a x-axis ranging from 0 to 3000, and xlim=-3 will res

ylim

A one- or two-value vector indicating the range of the y-axis. (See xlim) for more information.

main

Title for the plot. Empty by default. Note: the title can be added later using title.

xlab

Label for x-axis. Empty by default. If no label is provided, use mtext for adding axis labels.

ylab

Label for y-axis. Empty by default. (See xlab.)

h0

A vector indicating where to add solid horizontal lines for reference. By default no values provided.

v0

A vector indicating where to add dotted vertical lines for reference. By default no values provided.

bty

A character string which determined the type of box which is drawn about plots. If bty is one of "o", "l", "7", "c", "u", or "]" the resulting box resembles the corresponding upper case letter. A value of "n" (the default) suppresses the box.

eegAxis

Logical: whether or not to reverse the y-axis, plotting the negative amplitudes upwards as traditionally is done in EEG research. If eeg.axes is TRUE, labels for x- and y-axis are provided, when not provided by the user. Default value is FALSE.

...

Other arguments for plotting, see par.

Value

• An empty plot window.

See Also

Use title and mtext for drawing labels and titles; use lines and points for plotting the data; use legend for adding a legend. and acf_n_plots for inspection of individual time series.

Examples

data(simdat)
test <- simdat[simdat$Subject=='a10' & simdat$Trial==10,]

emptyPlot(range(test$Time), range(test$Y),
main='Data', ylab='Y', xlab='Time', 
h0=0, v0=c(0,1000,2000))
# Note that this is the same as:
emptyPlot(range(test$Time), range(test$Y))
title(main='Data', ylab='Y', xlab='Time')
abline(h=0)
abline(v=c(0,1000,2000), lty=3)

# To add data, use lines() and points()
lines(test$Time, test$Y)
