R 检查st_intesection是否为真/假Sf包

如何使用R中的sf包检查点是否与具有布尔结果的多边形相交

library(sf)
dub<- st_as_sf(data.frame(lon=72.917,lat=19.112), coords=c("lon","lat"),crs=4326)
a<- st_as_sf(data.frame(lon=72.930,lat=19.112), coords=c("lon","lat"), crs=4326)
buf<- st_buffer(a,0.01)

---

使用

st_相交

not

st_相交

并设置sparse=FALSE

> st_intersects(dub, buf, sparse = FALSE) 
# although coordinates are longitude/latitude, st_intersects assumes 
# that they are planar
#       [,1]
# [1,] FALSE

@sebdalgarno我对两个点（多边形内部和外部）

PointIN 1都错了

我的道歉-见修改后的回答我也遇到了多余的论点。无论如何，感谢您指出st_intersect:）

> st_intersects(dub, buf, sparse = FALSE) 
# although coordinates are longitude/latitude, st_intersects assumes 
# that they are planar
#       [,1]
# [1,] FALSE
