Usage

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.

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

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

## Powering
powering(y, 2)
