##### Add a Rug to a Plot

Adds a rug representation (1-d plot) of the data to the plot.

Keywords
aplot
##### Usage
rug(x, ticksize = 0.03, side = 1, lwd = 0.5, col = par("fg"),
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. Some devices will round the default width up to 1.

col

The colour the ticks are plotted in.

quiet

logical indicating if there should be a warning about clipped values.

further arguments, passed to axis, such as line or pos for specifying the location of the rug.

##### 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.
