toString.polynomial | R Documentation |
Creates a text representation for a polynomial, in the following scenarios:
if digits
is TRUE
then as.character(.)
is used
if digits
is FALSE
then ./.
is used
if digits
is numeric then as.character(round(., digits))
is used
## S3 method for class 'polynomial'
toString(
x,
digits = TRUE,
decreasing = FALSE,
variable = "x",
simplify = TRUE,
tol = 1e-09,
...
)

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