Do a ?geom_text in your console to read the manual. 

It's like this:

df <- data.frame(
  x = factor(c(1, 1, 2, 2)),
  y = c(1, 3, 2, 1),
  grp = c("a", "b", "a", "b")
)

ggplot(df) + geom_point(aes(x=x, y=y)) + geom_text(aes(x=x,y=y,label=grp),hjust=-0.7,vjust=-0.1,angle=45,size=12)

谢谢，我是想问把图中有背景颜色的也变为45度的怎么弄，p <- ggplot(mtcars, aes(wt, mpg, label = rownames(mtcars)))

p +geom_label(aes(fill=factor(cyl)))，然后怎么把他旋转。。
