## S3 method for class 'polynom'
plot(x, xlim = 0:1, ylim = range(Px), type = "l",
xlab = "x", ylab = "p(x)", ..., len = 1000)
## S3 method for class 'polylist'
plot(x, xlim = 0:1, ylim = range(Px), type = "l",
xlab = "x", ylab = "P(x)", ..., len = 1000)
## S3 method for class 'polylist'
lines(x, ..., len = 1000)
## S3 method for class 'polynom'
lines(x, ..., len = 1000)
## S3 method for class 'polylist'
points(x, ..., len = 100)
## S3 method for class 'polynom'
points(x, ..., at = seq(pu[1], pu[2], len = len), len = 100)

### Arguments

`x` |
A |

`xlim, ylim, xlab, ylab, type` |
As for |

`...` |
Additional arguments sent to |

`len` |
The number of linear line segments to use to present the polynomial curve. |

`at` |
the $x-$values where the points are to appear. |

### Details

`plot.polynom`

will by default choose `x`

limits to cover
the (real parts of) the zeros, stationary points and points of
inflexion of the ploynomial being plotted. `plot.polylist`

chooses by default an x region to accommodate all polynomials on the
list in this way. The current palette of colours is used for
different components. `lines.polynom`

may be used to add
individual polynomials to the plot. The argument `len`

may be
used to increase or decrease the number of straight line segments used
to represent the curves.

### Value

Nothing of use.
