In PolynomF: Polynomials in R

Plot method for polynomials

Description

Plot methods for polynom or polylist objects

Usage

## S3 method for class 'polylist'
plot(
  x,
  xlim = 0:1,
  ylim = range(Px),
  type = "l",
  xlab = "x",
  ylab = "P(x)",
  ...,
  col = seq_along(x),
  lty = if (length(col) == 1) seq_along(x) else "solid",
  len = 1000,
  legend = FALSE
)

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

## S3 method for class 'polynom'
lines(x, ..., len = 1000, limits = pu[1:2])

## S3 method for class 'polynom'
points(x, ..., len = 100, limits = pu[1:2])

## S3 method for class 'polylist'
lines(
  x,
  ...,
  len = 1000,
  limits = pu[1:2],
  col = seq_along(x),
  lty = if (length(col) == 1) seq_along(x) else "solid"
)

## S3 method for class 'polylist'
points(x, ..., len = 100)

Arguments

x	A polynom or polylist object to be plotted
xlim, ylim	as for graphics::plot
type	as for graphics::plot
xlab, ylab	as for graphics::plot
...	additional arguments passed on to methods
col, lty	Colour(s) and line type(s) as for graphics::plot
len	positive integer defining the point or curve resolution
legend	logical: for "polylist" objects, should a legend be drawn alongside the main plot?
limits	x-limits for the polynomial, default: the entire plot. For polylist objects this may be a two column matrix.

Value

Nothing of interest, invisibly

Examples

p <- poly_from_zeros((-3):4)
plot(p)
lines(deriv(p), col = "red")
