polylist: Lists of Polynomials

In eestileib/ComplexPoly: A Collection of Functions to Implement a Class for Univariate Polynomial Manipulations

Description

Create and manipulate lists of polynomials.

Usage

polylist(...)
as.polylist(x)
is.polylist(x)

Arguments

...	a list of R objects.
x	an R object.

Details

polylist takes a list of arguments, tries to convert each into a polynomial (see polynomial), and sets the class of the list to "polylist".

as.polylist tries to coerce its arguments to a polylist, and will do so for arguments which are polynomials or lists thereof.

is.polylist tests whether its argument is a polylist.

This class has several useful methods, such as taking derivatives (deriv) and antiderivatives (integral), printing and plotting, subscripting, computing sums and products of the elements, and methods for c, rep, and unique.

Examples

## Calculate orthogonal polynomials
pl <- poly.orth(rep(1:4, 1:4), 3)
pl
plot(pl)
deriv(pl)
integral(pl)
sum(pl)
prod(pl)
unique(rep(pl, 3)[c(8, 12)])
