Plot a balance with node labels under horizontal branches

Plot a balance with node labels under horizontal branches

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])
             })
