更新了答案，以考虑顺时针方向前进的闭合多边形会形成一个孔。

library(ggplot2)
bndBox <- data.frame(x=c(-Inf,-Inf,Inf,Inf, -Inf),
                     y=c(-Inf,Inf,Inf,-Inf, -Inf),
                     id="bnd")
bndBox <- data.frame(x=c(-1,1,1,-1, -1),
                     y=c(-1,-1,1,1, -1),
                     id="bnd")
hole <- data.frame(
  x = cos(seq(0, 2*pi, length.out = 360)) * 0.95,
  y = sin(seq(0, 2*pi, length.out = 360)) * 0.95,
  id="circle"
)
porthole <- rbind(bndBox,hole)
ggplot() + 
  geom_polygon(data=porthole, 
               aes(x = x, y = y), fill = "red")+
  geom_point(aes(x = 0, y = 0)) +
  coord_fixed() +
  theme_void()

我可以用sf做我想做的事情，但我希望不要走这条路，因为我发现代码很难理解，并且觉得geom_polygon（）应该能够处理它。下面是一个繁琐的解决方案：

library(ggplot2)
library(sf)
bndBox <- data.frame(x=c(-1,1,1,-1),
                     y=c(1,1,-1,-1),
                     id="bnd")
hole <- data.frame(
  x = cos(seq(0, 2*pi, length.out = 360)),
  y = sin(seq(0, 2*pi, length.out = 360)),
  id="circle"
)
portholeSF <- st_sfc(
  st_polygon(
    list(
      hole = cbind(
        c(hole$x,hole$x[1]), 
        c(hole$y,hole$y[1])
      ),
      bnd = cbind(
        c(bndBox$x,bndBox$x[1]), 
        c(bndBox$y,bndBox$y[1])
      )
    )
  )
)
ggplot() + 
  # I want to see this point
  geom_point(aes(x = 0,y = 0)) +
  # But not this point
  geom_point(aes(x = -0.75,y = 0.75)) +
  geom_sf(data = portholeSF)
