Description

highlights the two direct descendant clades of an internal node

Usage

geom_balance(
  node,
  fill = "steelblue",
  color = "white",
  alpha = 0.5,
  extend = 0,
  extendto = NULL
)

Arguments

node	selected node (balance) to highlight its two direct descendant
fill	color to fill in the highlight rectangle, default to "steelblue"
color	color to outline highlight rectangle and divide balance, defaults to "white"
alpha	alpha (transparency) for the highlight rectangle, defaults to 0.5
extend	extend xmax of the highlight rectangle by the value of extend
extendto	extend xmax of the highlight rectangle to the value of extendto
