as_Spatial Error when converting sf object to sp

Question

I am working on the example for as_Spatial which is giving me the following error :

Error in sp::CRS(SRS_string = from$wkt) : unused argument (SRS_string = from$wkt)

nc <- st_read(system.file("shape/nc.shp", package="sf"))
spdf <- as_Spatial(nc)
as(st_geometry(nc), "Spatial")

both codes for transforming from sf to sp gives the same error

Answer 1

Your codes run fine in my Windows 10 computer. Also, comments provided above should work. However, you can try this:

nc <- st_read(system.file("shape/nc.shp", package="sf"))
nc_sp <- as(nc, Class = "Spatial") # converts sf object to sp object
