\name{clock24.plot}
\title{Plot values on a 24 hour "clockface"}
\usage{
clock24.plot(lengths,clock.pos,labels=NULL,label.pos=NULL,rp.type="r",...)
}
\alias{clock24.plot}
\arguments{
\item{lengths}{numeric data vector. Magnitudes will be represented as
line lengths, or symbol or polygon vertex positions.}
\item{clock.pos}{numeric vector of positions on the 'clockface'.
These must be in decimal hours and will be rescaled to radians.}
\item{labels}{Labels to place at the circumference.}
\item{label.pos}{Radial positions of the labels.}
\item{rp.type}{Whether to plot radial lines, symbols or a polygon.}
\item{...}{additional arguments are passed to \samp{radial.plot} and
then to \samp{plot}.}
}
\description{
\samp{clock24.plot} displays a plot of radial lines, symbols or a polygon
centered at the midpoint of the plot frame on a 24 hour 'clockface'.
In contrast to the default behavior of \samp{radial.plot}, the positions
are interpreted as beginning at vertical (000) and moving clockwise.
If \samp{add=TRUE} is passed as one of the additional arguments, the values
will be added to the current plot. If a \samp{radial.lim} argument was
passed on the initial plot, it must be passed again to add values or the
values will be displayed incorrectly.
}
\value{A list of the parameters altered by \link{radial.plot}.}
