## Coercion with `as.numeric` or `as.integer` don't work the way we want.
print(as.numeric(object))
print(as.integer(object))
object <- factorize(object)
print(object)

## DFrame ====
object <- S4Vectors::DataFrame(
    "a" = as.factor(c(100L, 100L, 101L, 101L)),
    "b" = as.factor(c("a", "b", "a", "b"))
)
print(object)
object <- unfactorize(object)
print(object)
