xlimやylimを使ってggrepelの重なり点を止めるには

Question

私は本当に非常に単純なグラフ作成で苦労しています。私はXLIM使用して、右上の象限にラベルを制限しようとする場合は

：私は次のような画像を得る

> vol+geom_label_repel(data = subset(data, color=="Increased"), aes(label=gene)) 

：私の火山プロットのためのRで次のコードで

：

私が入力したxlimまたはylimの値は問題ではありません。また、コードのどこに行くかは関係ありません。

右上の四分円に点を重ならないようにラベルを貼る方法は誰にも分かりますか？ここで

Answer 1

はgeom_label_repelでxlimとylimの使用例である：

library(ggplot2) 
library(ggrepel) 
set.seed(1) 
iris2 <- iris[sample(1:nrow(iris), 20),] 
ggplot(iris2, aes(x=Sepal.Length,y=Sepal.Width)) + 
geom_point() + 
geom_label_repel(aes(label=Species), xlim=c(6,8), ylim=c(3.2,4))
