plot_balance: Plot a balance with node labels under horizontal branches

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

Plot a balance with node labels under horizontal branches

Description

Plot a balance with node labels under horizontal branches

Usage

plot_balance(
  B,
  data = NULL,
  main = "Balance dendrogram",
  summary_fun = NULL,
  cex_node = 0.9,
  offset_node = 0.05,
  ...
)

Arguments

B	Balance basis matrix
data	Optional compositional data used to compute balance summaries
main	Plot title
summary_fun	Optional function applied to each balance coordinate vector. It must take a numeric vector and return a character string.
cex_node	Character expansion for node labels
offset_node	Vertical offset below the horizontal branch, relative to max height
...	Further arguments passed to plot

Value

Invisibly returns a data.frame with node coordinates and labels

Examples

X = waste[,5:9]
B = pb_basis(X, method = 'exact')

plot_balance(B)

plot_balance(B, data = X,
             summary_fun = function(x){
               q = quantile(x, probs = c(0.25, 0.5, 0.75))
               sprintf("%0.2f [%0.2f-%0.2f]", q[2], q[1], q[3])
             })
