toLatex.polynomial: LaTeX Representation of a Polynomial

Description

Returns a LaTeX representation of the polynomial.

Usage

# S3 method for polynomial
toLatex(
  object,
  digits = TRUE,
  decreasing = FALSE,
  variable = "x",
  simplify = TRUE,
  tol = 1e-09,
  ...
)

Value

A character

Arguments

object

polynomial

digits

numeric or logical: how to convert to text (default: NA)

decreasing

logical: order of the terms by increasing or decreasing powers (default: FALSE)

variable

character: name of variable used (default: "x")

simplify

logical: should the polynomial representation be simplified (default: TRUE)

tol

numeric: tolerance (default: 1e-9). A negative value will keep zeros and ones too, but:

• If a coefficient is smaller than tol then zero terms are not kept

• If a absolute value of coefficient minus one is smaller than tol then coefficient is not kept

...

unused parameters

Examples

p <- polynomial(c(-1,0,2)/3)
toLatex(p, 4)
toLatex(p, FALSE)
toLatex(p, TRUE)
toLatex(p, variable="z")
toLatex(p, decreasing=TRUE)
p <- polynomial(c(0,1,2)/3)
toLatex(p)
toLatex(p, tol=-1)
