Add a Rug to a Plot
Description
Adds a rug representation (1-d plot) of the data to the plot.
Usage
rug(x, ticksize=0.03, side=1, lwd=0.5, col,
quiet = getOption("warn") < 0, ...)
Arguments
x |
A numeric vector |
ticksize |
The length of the ticks making up the ‘rug’. Positive lengths give inwards ticks. |
side |
On which side of the plot box the rug will be plotted. Normally 1 (bottom) or 3 (top). |
lwd |
The line width of the ticks. |
col |
The colour the ticks are plotted in, default is black. |
quiet |
logical indicating if there should be a warning about clipped values. |
... |
further arguments, passed to |
Details
Because of the way rug is implemented, only values of x
that fall within the plot region are included. There will be a
warning if any finite values are omitted, but non-finite values are
omitted silently.
Because of the way colours are done the axis itself is coloured the same as the ticks. You can always replot the box in black if you don't like this feature.
