畫圓形樹形圖的時(shí)候 正常出圖如下
library(ggplot2)
library(ggtree)
set.seed(2017-02-16)
tree1 <- rtree(50)
ggtree(tree1,layout = "circular",
branch.length = "none")+
geom_tiplab()
image.png
如果要增加中心的空白區(qū)域顽决，可以使用xlim()函數(shù)來調(diào)節(jié)
library(ggplot2)
library(ggtree)
set.seed(2017-02-16)
tree1 <- rtree(50)
ggtree(tree1,layout = "circular",
branch.length = "none")+
geom_tiplab()+
xlim(-20,NA)
