As the actual CRS is unknown, **spData** reports missing, although it may very well be `+proj=longlat +datum=NAD27`

```{r echo=TRUE,eval=TRUE}
st_crs(nc) <- "+proj=longlat +datum=NAD27"
```
As the actual CRS was unknown, the GeoPackage **spData** version has been updated to `"EPSG:4267"`.

Next, are the geometries the same? `sf::st_equals` returns a logical matrix, so we'll check that the diagonal values are all `TRUE`, and that only those values are `TRUE` by summing and recalling that `n` is `100`:
