Arguments

x,y vectors containing the coordinates of the vertices of the polygon.
density density of fill pattern. NOT YET implemented.

... graphical parameters can be given as arguments to polygon, must importantly,

Examples

n <- 100
xx <- c(0:n, n:0)
yy <- c(c(0,cumsum(rnorm(n))), rev(c(0,cumsum(rnorm(n)))))
plot   (xx, yy, type="n", xlab="Time", ylab="Distance")
polygon(xx, yy, col="gray", border = "red")
