如何在ggplot2中添加X和Y点坐标？

Question

我正在尝试制作 ggplot，如何添加点的 x 和 y 坐标？我尝试了这段代码，但它不起作用：

d4<-Restriangle[1:(n-1),5]
xaxis=c(1:(n-1))
yaxis=Restriangle[1:(n-1),4]
data=data.frame(xaxis,yaxis)
library(ggplot2)
res=ggplot(df, aes(x = d, y = d4)) +  
# Set up canvas with outcome variable on y-axis
geom_point(data=data,size=4, shape=19,color = "blue"),aes(x = xaxis, y 
 = yaxis) )  
# Plot the actual points
res

当这样做时我得到这个

如何添加 XY 点坐标？

您在寻找类似 geom_labels 的东西吗？

x <- c(1,3,4,6,9)
y <- x^2
coords = paste(x,y,sep=",")

df = data.frame(x,y)

ggplot(df,aes(x,y))+geom_point(col="blue")+
  geom_label(aes(x+.5,y+0.5,label=coords))
