Usage

"st_geometry"(obj, ...)
st_geometry(obj, ...)
"st_geometry"(obj, ...)
"st_geometry"(obj, ...)

st_geometry(x) <- value

Arguments

obj

object of class sf or sfc

...

ignored

x

object of class data.frame

value

object of class sfc

Value

st_geometry returns an object of class sfc, a list-column with geometriesst_geometry returns an object of class sfc. Assigning geometry to a data.frame creates an sf object, assigning it to an sf object replaces the geometry list-column.

Examples

df = data.frame(a = 1:2)
sfc = st_sfc(st_point(c(3,4)), st_point(c(10,11)))
st_geometry(sfc)
st_geometry(df) <- sfc
class(df)
st_geometry(df)
st_geometry(df) <- sfc # replaces
