如何使用geom_text（）或geom_label（）精确定位ggplot（）的文本标签。 geom_text_repel（）无效。如果使用则会引发错误

Question

我尝试了geom_text()的许多组合，但无法获得我需要的确切输出。

我希望标签保持在相同的y轴极限，除非它们相交如果它们相交，我需要它们在y方向上偏移，这样它们就不会相交。我希望它们高效，以便它们之间没有多少空间。

geom_text_repel()不是修复，因为它会引发一些错误。有人可以解释我使用geom_text_repel()

时出错的原因

这是我的数据和代码：

library(ggplot2)
library(ggrepel)
Data=data.frame(Group=c("Group 2","Group 1","Group 3","Group 2","Group 5","Group 4","Group 6",
                        "Group 7","Group 4","Group 3","Group 1","Group 5","Group 6","Group 7",
                        "Group 2","Group 4","Group 6","Group 7","Group 3","Group 1"),
                Fruit=c("apple","apple","apple","mango","apple","apple","apple","apple","mango","mango",
                        "mango","mango","mango","mango","orange","orange","orange","orange","orange",
                        "orange"),
                Percentage=c(68.46846847,77.35849057,72.72727273,26.12612613,76.31578947,62.79069767,
                             71.05263158,69.23076923,30.23255814,25,20.75471698,23.68421053,23.68421053,
                             23.07692308,5.405405405,6.976744186,5.263157895,7.692307692,2.272727273,
                             1.886792453))
ggplot(Data,aes(x=reorder(Fruit,Percentage),y=Percentage,color=Group,label=paste0(round(Percentage),"%")))+geom_point(size=4)+coord_flip()+scale_y_continuous(limits=c(0,100))+
  theme(panel.grid.major.y=element_line(color="gray90",size = 0.7),panel.background=element_blank(),strip.background=element_blank(),panel.border=element_rect(color="black",fill=NA,size=1))+
  labs(x="",y="% of people",color="")+geom_text_repel(aes(label=paste0(round(Percentage),"%")))

错误是：

Error in .Call("_ggrepel_repel_boxes", PACKAGE = "ggrepel", data_points,  : 
  Incorrect number of arguments (11), expecting 9 for '_ggrepel_repel_boxes'

这是我的输出：

这就是我想要的：

你必须使用geom_text_repel的参数，但这可能是一个起点：

library(ggrepel)
library(ggplot2)
ggplot(Data,aes(x=reorder(Fruit,Percentage),y=Percentage,
                color=Group,
                label=paste0(round(Percentage),"%")))+
  geom_point(size=4)+
  coord_flip()+scale_y_continuous(limits=c(0,100))+
  theme(panel.grid.major.y=element_line(color="gray90",size = 0.7),
        panel.background=element_blank(),
        strip.background=element_blank(),
        panel.border=element_rect(color="black",fill=NA,size=1))+
  labs(x="",y="% of people",color="")+
  ggrepel::geom_text_repel(direction = "y", 
                           segment.colour = "transparent",
                           nudge_x = 0.2, point.padding = 0.1, box.padding = 0.1)
