points(p, length = 100, ...)
p
| An object of class polynomial |
length
| Size of x vector at which evaluations are to be made |
...
| Additional arguments as for the points generic |
Points representing the given polynomial are added to an existing plot. Values outside the current plot region are not shown.
p <- poly.from.zeros(-1:5) plot(p) lines(poly.from.zeros(2:4), lty=2) points(poly.from.zeros(-2:6), pch=4)
