\name{thigmophobe}
\alias{thigmophobe}
\title{Find the direction away from the closest point}
\description{Find the direction away from the closest point}
\usage{
thigmophobe(x,y=NULL,names=seq_along(z),xlog=par("xlog"),ylog=par("ylog"),
usr=par("usr"),pin=par("pin"),eps=.Machine$double.eps,pi=base::pi)
}
\arguments{
\item{x,y}{Numeric data vectors. Typically the x/y coordinates of
plotted points. If arrays are passed, they will be silently coerced to
numeric vectors.}
\item{names}{Names for the vector of directions.}
\item{xlog,ylog}{Flags for logarithmic axes. See Note.}
\item{usr}{The extent of the plot in user units.}
\item{pin}{Extent of the plot in inches.}
\item{eps}{smallest number that can be represented on the system.}
\item{pi}{value of pi.}
}
\details{
\samp{thigmophobe} returns the direction (as 1|2|3|4 - see pos= in
\samp{text}) away from the nearest point to each of the points
described by \samp{x} and \samp{y}.
}
\note{
\samp{thigmophobe} is typically used to get the offsets to automatically
place labels on a scatterplot or similar using \samp{thigmophobe.labels}
to avoid overlapping labels. The name means "one who fears being touched".
The \samp{plot.span}, \samp{xlog} and \samp{ylog} arguments were added to
allow \samp{thigmophobe} to be used outside of base graphics.
}
\value{
A vector of directions away from the point nearest to each point.
