scalar function

Scalar Product

Computes the Aitchison scalar product of two compositions. methods

scalar(x, y, ...)

## S4 method for signature 'numeric,numeric'
scalar(x, y)

## S4 method for signature 'CompositionMatrix,CompositionMatrix'
scalar(x, y)

Arguments

• x, y: A CompositionMatrix object.
• ...: Currently not used.

Returns

A numeric vector.

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)
