\title{Add an Inverse Rug to a Plot}
\description{Adds a \emph{rug} representation (1D plot) of the data to the plot,
but with the coloring inverted.}
\usage{
ruginv(x,ticksize=0.03,side=1,lwd=0.5,col=par("fg"),col.ticks="white",
quiet=getOption("warn") < 0,...)
}
\arguments{
\item{x}{A numeric vector.}
\item{ticksize}{The length of the ticks making up the 'rug'. Positive lengths
produce inward ticks.}
\item{side}{On which side of the plot box the rug will appear. Usually 1
(bottom) or 3 (top).}
\item{lwd}{The line width of the ticks.}
\item{col}{Color of the background of the ticks.}
\item{col.ticks}{The color of the ticks.}
\item{quiet}{Logical indicating if there should be a warning about clipped
values.}
\item{...}{Further arguments passed to \link{polygon} when plotting the
background for the ticks.}
