pb_subcomposition: Recursive constrained principal balances on subcompositions

In coda.base: A Basic Set of Functions for Compositional Data Analysis

Recursive constrained principal balances on subcompositions

Description

Recursively construct balances on selected subcompositions, optionally enforcing groups of variables to remain together through constraints.

Usage

pb_subcomposition(
  X,
  variables = seq_len(ncol(X)),
  constraints = NULL,
  angle = FALSE
)

Arguments

X	Compositional data set.
variables	Indices of the variables currently considered.
constraints	Optional list of groups of variables to be constrained together during the recursive search.
angle	Logical; if 'TRUE', use the angle criterion instead of the variance criterion when computing constrained balances.

Value

A list of balance vectors.
