balance_dendrogram: Compositional Balance Dendrogram

Description

Plots a balance dendrogram based on a compositional data set and a corresponding balance matrix. This visualization helps interpret the structure of balances in compositional data analysis.

Usage

balance_dendrogram(X, B, group = NULL)

Value

A 'ggplot2' object representing the balance dendrogram.

Arguments

X

A numeric matrix or data frame representing the compositional data. Rows are observations and columns are components (must be strictly positive).

B

A numeric matrix representing the balance basis (e.g., an isometric log-ratio (ilr) balance matrix).

group

Show boxplot by groups

Details

The dendrogram shows the hierarchical structure of balances derived from the balance matrix B. Each internal node corresponds to a balance, and the height or color may reflect the variance explained or other statistics.

Examples

# Simulated compositional data and balances
X = matrix(runif(50, 1, 10), ncol = 5)
colnames(X) = LETTERS[1:5]
B = pb_basis(X, method = 'exact')
balance_dendrogram(X, B)
