这是我用过的代码。

grid 但是得到了错误 Error: Don't know how to add roundrectGrob(x = 28, y = -2.3, width = 22, height = 0.45) to a plot

library(ggplot2)
p <- ggplot() +
ylim(-4, 4) +
xlim(0, 100)
## First rect
p <- p + geom_rect(mapping=aes(xmin=10,
xmax=90,
ymin=-2.15,
ymax=-2.00),
colour = "black",
fill = "grey")
## Second rect
p <- p + geom_rect(mapping=aes(xmin=28,
xmax=50,
ymin=-2.30,
ymax=-1.85),
colour = "black",
fill = "red")
# print
p
dev.off()

按照@hrbrmstr的建议,安装后 statebins

devtools::install_github("hrbrmstr/statebins")

试试这个

library(ggplot2)
p <- ggplot() + ylim(-4, 4) + xlim(0, 100)
## First rect
p <- p + geom_rect(mapping=aes(xmin=10,
         xmax=90, ymin=-2.15,  ymax=-2.00),
         colour = "black", fill = "grey")
## Second rect
p <- p + statebins:::geom_rrect(mapping=aes(xmin=28, 
         xmax=50, ymin=-2.30, ymax=-1.85),  
         colour = "black", fill = "red")
# Print
p
