toLatex.polynomial

Description

Returns a LaTeX representation of the polynomial.

Usage

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

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. 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

Value

character

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)
