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 aslineorposfor 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.
