Usage

polygon(x, y, col=NULL, border=NULL, ...) {
}
{polygon}
{
\item{x,y}{vectors containing the coordinates of the vertices
of the polygon.}
\item{col}{an integer specifying the color to be used in
filling the polygon.  The default is to leave polygons unfilled.}
\item{border}{the color to draw the border.  The default is to
leave the border undrawn.}
\item{...}{graphical parameters can be given as arguments to polygon.}
}
{
polygon draws the polygons whose vertices are
given in x and y.
Note that if neither of col or border is specified
then nothing is drawn.
}
{
  segments for even more flexibility,
  lines, rect, box, abline.
