我试图想象我的ggtree,我似乎被困在最后一步;将树标签从水平重新定位到垂直,使它们不重叠。如果我更改 geom_tiplab 函数上的 geom = "text",我会得到我想要的,但我的标签不再是彩色的。这里和这里的数据集
这是可重复性的代码;请帮忙
p1 <- ape::read.tree("Tert_aln.fasta_processed.fa.raxml.support")
temp1 = read.csv("Tert_Final_Mapping_File.csv", sep=";")
mycolors = c(brewer.pal(name="Set1", n = 9), brewer.pal(name="Paired", n = 12), brewer.pal(name="Dark2", n = 8))
p2 <- ggtree(p1, layout='circular') %<+% temp1 +
geom_tippoint(
mapping = aes(color = phylum), # tip color by phyla.
size = 2,
show.legend = FALSE) +
scale_color_manual(values = mycolors) +
geom_tiplab( # adds name of phyla to tip of its branch
aes(fill = phylum),
color = 'black',
offset = 2,
size = 3,
geom = "label",
align = TRUE,
face = "bold",
label.size = 0
label.padding = unit(0.15, "lines"), # amount of padding around the labels
linetype = "solid") +
ggtitle("Phylogenetic tree of Tert")+ # title of your graph
theme(
axis.title.x = element_blank(), # removes x-axis title
axis.title.y = element_blank(), # removes y-axis title
legend.title = element_text( # defines font size and format of the legend title
face = "bold",
size = 12),
legend.text=element_text( # defines font size and format of the legend text
