Summary and Math methods for polynomials

Description

These provide methods for the generic function Summary and Math for polynomial and polylist objects. For Summary only sum and prod members are implemented

Usage

## S3 method for class 'polynom'
Summary(..., na.rm = FALSE)

## S3 method for class 'polylist'
Summary(..., na.rm = FALSE)

## S3 method for class 'polynom'
Math(x, ...)

## S3 method for class 'polylist'
Math(x, ...)

Arguments

`...`	Additional arguments
`na.rm`	Logical: should missing values be removed?
`x`	a `"polynom"` or `"polylist"` objects.

Value

The result of the group generic operation

Examples

lis <- as_polylist(lapply(-2:3, function(x) polynomial() - x))
prod(lis)
sum(lis)
solve(prod(lis))
solve(sum(lis))
