Lines Method for Polynomials

Add a polynomial to an existing plot usually as a line plot.

## S3 method for class 'polynomial'
lines(x, len = 1000, xlim = NULL, ylim = NULL, ...)

`x`	an object of class `"polynomial"`.
`len`	size of vector at which evaluations are to be made.
`xlim, ylim`	the range of x and y values with sensible defaults.
`...`	additional arguments as for the `lines` generic.

This is a method for the generic function lines.

Lines representing the given polynomial are added to an existing plot. Values outside the current plot region are not shown.

plot  (poly.calc(-1:5))
lines (poly.calc( 2:4), lty = 2)
points(poly.calc(-2:6), pch = 4)
