In YuLab-SMU/ggtree: an R package for visualization of tree and annotation data

geom_strip

Description

annotate associated taxa (from taxa1 to taxa2, can be Monophyletic, Polyphyletic or Paraphyletc Taxa) with bar and (optional) text label

Usage

geom_strip(
  taxa1,
  taxa2,
  label,
  offset = 0,
  offset.text = 0,
  align = TRUE,
  barsize = 0.5,
  extend = 0,
  fontsize = 3.88,
  angle = 0,
  geom = "text",
  hjust = 0,
  color = "black",
  fill = NA,
  family = "sans",
  parse = FALSE,
  ...
)

Arguments

taxa1	taxa1
taxa2	taxa2
label	add label alongside the bar (optional)
offset	offset of bar and text from the clade
offset.text	offset of text from bar
align	logical, whether to align bars to the most distant bar ,defaults to "TRUE" Note that if "FALSE", the bars might cross the tree
barsize	set size of the bar
extend	extend bar length vertically
fontsize	set size of the text
angle	set the angle of text
geom	one of 'text' or 'label'
