components: Polynomial components

Description

Compute quantities/expressions related to a multivariate polynomial.

Usage

# S3 method for mpoly
[(x, ndx)
LT(x, varorder = vars(x), order = "lex")
LC(x, varorder = vars(x), order = "lex")
LM(x, varorder = vars(x), order = "lex")

reduced

if TRUE, don't include zero degrees

Value

An object of class mpoly or mpolyList, depending on the context
