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

geom_tree

Description

add tree layer

Usage

geom_tree(
  mapping = NULL,
  data = NULL,
  layout = "rectangular",
  multiPhylo = FALSE,
  continuous = "none",
  position = "identity",
  ...
)

Arguments

mapping	aesthetic mapping
data	data of the tree
layout	one of 'rectangular', 'dendrogram', 'slanted', 'ellipse', 'roundrect', 'fan', 'circular', 'inward_circular', 'radial', 'equal_angle', 'daylight' or 'ape'
multiPhylo	logical, whether input data contains multiple phylo class, defaults to "FALSE".
continuous	character, continuous transition for selected aesthethic ('size' or 'color'('colour')). It should be one of 'color' (or 'colour'), 'size', 'all' and 'none', default is 'none'
position	Position adjustment, either as a string, or the result of a call to a position adjustment function, default is "identity".
...	additional parameter some dot arguments: nsplit integer, the number of branch blocks divided when 'continuous' is not "none", default is 200.

Value

tree layer

Aesthetics

• color character, control the color of line, default is black (continuous is "none").

• linetype control the type of line, default is 1 (solid).

• linewidth numeric, control the width of line, default is 0.5 (continuous is "none").
