我在R中有这个圆形树状图,我想放大它。我该如何进行? 这里是:
使用了以下代码:
library(dendextend)
library(circlize)
load(file = "hc1.rda")
#out1 <- cutree(hc1, k = 50)
load(file = "out1.rda")
dend <- as.dendrogram(hc1)
dorder <- order.dendrogram(dend)
colrs = colorRampPalette(c("blue", "red"))(50)
#library(colorBrewer)
# modify the dendrogram to have some colors in the branches and labels
dend1 <- color_branches(dend, col=colrs ,
clusters=out1)
#plot(dend1)
# plot the radial plot
par(mar = rep(0,4))
circlize_dendrogram(dend1, labels_track_height = NA,
dend_track_height = .4, labels = FALSE)
答案 0 :(得分:0)
已经晚了,但我尝试了另一种方法来解决此问题。导出图像/ pdf时,我通常将尺寸更改为4的倍数。希望对您有所帮助。
