| rug {graphics} | R Documentation |
Adds a rug representation (1-d plot) of the data to the plot.
rug(x, ticksize = 0.03, side = 1, lwd = 0.5, col = par("fg"),
quiet = getOption("warn") < 0, ...)
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 |
col |
The colour the ticks are plotted in. |
quiet |
logical indicating if there should be a warning about clipped values. |
... |
further arguments, passed to |
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.
