Operations in the Simplex

Operators performing operations in the simplex. methods

x %perturbe% y

x %power% y

## S4 method for signature 'CompositionMatrix,CompositionMatrix'
x %perturbe% y

## S4 method for signature 'CompositionMatrix,numeric'
x %power% y

## S4 method for signature 'numeric,CompositionMatrix'
x %power% y

Arguments

• x: A CompositionMatrix object.
• y: A CompositionMatrix object or a numeric vector.

Returns

A CompositionMatrix object or a numeric vector (same as x).

Details

• %perturbe%: Perturbation operation .
• %power%: Powering operation .

Examples

x <- as_composition(c(1, 2, 3))
y <- as_composition(c(1, 2, 1))

## Perturbation
perturbation(x, y)
x + y

## Powering
powering(y, 2)
y * 2

## Scalar product
scalar(x, y)
