To drop the geometry column, use st_drop_geometry():

library(sf)nc % st_drop_geometry()class(nc_df2)#> <1> “data.frame”Before st_drop_geometry() was added to the sf package (in November, 2018), one could produce the same result using the st_set_geometry() function, like this:

library(sf)nc <1> “sf” “data.frame”nc_df % st_set_geometry(NULL)class(nc_df)#> <1> “data.frame”
