accessor: Accessor methods for freealg objects

In RobinHankin/freealg: The Free Algebra

Accessor methods for freealg objects

Description

Accessor methods for free algebra objects

Usage

words(x)
coeffs(x,drop=TRUE)
coeffs(x) <- value

Arguments

x	Object of class freealg
value	Numeric vector of length 1
drop	Boolean, with default TRUE meaning to drop the disord attribute, as per disordR::drop() and FALSE meaning to consistently return a disord object irregardless

Details

Access or set the different parts of a freealg object. The constant term is technically a coefficient but is documented under constant.Rd.

“Pure” extraction and replacement (as in a[i] and a[i] <- value is implemented exprimentally. The code for extraction is cute but not particularly efficient.

Note

There is an extended discussion of disordR discipline in the context of algebras in the mvp package at accessor.Rd.

Examples

a <- rfalg()
a
coeffs(a)
words(a)  # NB: hash is identical to that of coeffs(a)

coeffs(a) <- 7   # replacement methods work 
a
coeffs(a)  #
