垂直中心线
Vertical Centre Line
对于下面的示例,我想在 x 轴的值 1 处添加一条垂直中心线。我尝试了 geom_estci
(http://ggepi.lukewjohnston.com/reference/geom_estci.html),但我的 R 没有找到 geom_estci
函数。我同时安装了库 ggplot2 和扫帚。我试图安装 ggepi 库。但它不适用于 R 版本 3.6.1。对于以下示例,我如何在 x=1 处添加一条垂直中心线?
d=data.frame(drink=c("coffee","tea","water"), mean=c(3,6,2), lower=c(2.6,5.6,1.8),
upper=c(3.5,6.3,2.8))
ggplot() +
geom_errorbarh(data=d, mapping=aes(y=drink, x=upper, xmin=upper, xmax=lower), height=0.2, size=1,
color="blue") +
geom_point(data=d, mapping=aes(y=drink, x=mean), size=4, shape=21, fill="white")
尝试添加 geom_vline(xintercept = 1)
.
