\title{ Adds a "push pin" to an existing 3-d plot}
\description{Adds to an existing 3-d perspective plot
a push pin to locate a specific point.}
\usage{
pushpin( x,y,z,p.out, height=.05,col="black",text=NULL,adj=-.1,cex=1.0,...)
}
\arguments{
\item{x}{x location}
\item{y}{y location}
\item{z}{z location}
\item{p.out}{Projection information returned by persp}
\item{height}{Height of pin in device coordinates (default is about
5\% of the vertical distance ). }
\item{col}{Color of pin head.}
\item{text}{Optional text to go next to pin head.}
\item{adj}{Position of text relative to pin head.}
\item{cex}{Character size for pin head and/or text}
