Arguments
el
a vector with the electrode to be plotted.
startmsec
the start time (in ms) of the ERP vector.
endmsec
the end time (in ms) of the ERP vector.
smo
the smoothing parameter to apply (see smooth.spline). Default is NULL and no smoothing is applied.
interval
a vector with a pair of values indicating the interval (in milliseconds) to be plotted.
xlim
a vector with a pair of values indicating the limits (in milliseconds) of the x axis.
ylim
a vector with a pair of values indicating the limits (in milliseconds) of the x axis.
col
the color of the ERP waveform.
lwd
the line width of the ERP waveform.
xlab
the label of the x axis.
ylab
the label of the y axis.
main
the title of the plot.
frame.plot
a logical indicating whether a box should be drawn around the plot.
draw.xaxis
a logical indicating whether the x axis should be drawn.
draw.yaxis
a logical indicating whether a box should be drawn around the plot.
type
1-character string giving the type of plot desired. Default is "l" and a line will be plotted. If "n" the ERP waveform is not plotted (see plot.default).
x0
a logical indicating whether a short segment should be drawn to indicate the 0 point (in millisecond)
x.tick
the position (in milliseconds) of x ticks.
x.labels
the labels (usually a vector of numbers) to be plotted on the x axis.
x.pos
the position of x axis, in terms of y axis coordinates. Default is NA and the axis is drawn at the bottom of the plot.
x.outer
a logical value indicating whether the x axis should be drawn in the outer plot margin, rather than the standard plot margin.
x.font
font for text of x labels. Defaults to par("font").
x.lty
line type for both the x axis line and the x tick marks.
x.lwd
line width for the x axis line.
x.lwd.ticks
line width for the x tick marks.
x.col
colors for the x axis line and the x tick marks.
x.col.ticks
color for the x tick marks (if specified, override x.col)
x.hadj
adjustment (see par("adj")) for all x labels parallel ("horizontal") to the reading direction. If this is not a finite value, the default is used (centring for strings parallel to the axis, justification of the end nearest the axis otherwise).
x.padj
adjustment for each x tick label perpendicular to the reading direction. For labels parallel to the axes, padj = 0 means right or top alignment, and padj = 1 means left or bottom alignment. This can be a vector given a value for each string, and will be recycled as necessary.
x.tcl
The length of tick marks as a fraction of the height of a line of text. The default value is -0.5.
x.tick.both
Logical. Should the tick marks be drawn both above and below the x axis?
x.cex
The magnification to be used for the x labels.
y.tick
the position (in milliseconds) of y ticks.
y.labels
the labels (usually a vector of numbers) to be plotted on the y axis.
y.pos
the position of y axis, in terms of x axis coordinates. Default is NA and the axis is drawn at the left of the plot.
y.outer
a logical value indicating whether the y axis should be drawn in the outer plot margin, rather than the standard plot margin.
y.font
font for teyt of y labels. Defaults to par("font").
y.lty
line type for both the y axis line and the y tick marks.
y.lwd
line width for the y axis line.
y.lwd.ticks
line width for the y tick marks.
y.col
colors for the y axis line and the y tick marks.
y.col.ticks
color for the y tick marks (if specified, override y.col)
y.hadj
adjustment (see par("adj")) for all y labels parallel ("horizontal") to the reading direction. If this is not a finite value, the default is used (centring for strings parallel to the axis, justification of the end nearest the axis otherwise).
y.padj
adjustment for each y tick label perpendicular to the reading direction. For labels parallel to the ayes, padj = 0 means right or top alignment, and padj = 1 means left or bottom alignment. This can be a vector given a value for each string, and will be recycled as necessary.
y.tcl
The length of tick marks as a fraction of the height of a line of teyt. The default value is -0.5.
y.tick.both
Logical. Should the tick marks be drawn both above and below the y axis?
y.cex
The magnification to be used for the y labels.
