closure function

Closure Operation

Closes compositions to sum to 1. methods

closure(x, ...)

## S4 method for signature 'numeric'
closure(x, total = 1, na.rm = TRUE)

## S4 method for signature 'matrix'
closure(x, total = 1, na.rm = TRUE)

Arguments

• x: A numeric vector or matrix.
• ...: Currently not used.
• total: A numeric vector specifying the total amount to which the compositions should be closed (defaults to 1).
• na.rm: A logical scalar: should missing values be removed?

Returns

A numeric vector or matrix (same as x).

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)
