R: Summary and Math methods for polynomials

GroupGenerics {PolynomF} | R Documentation

## 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))
