  .problem,
  quiet = xpdb$options$quiet,
  ...,
  group_vars = "id"
)

if (!rlang::is_installed("rxode2") ||
   !exists("rxDerived", envir = rlang::ns_env("rxode2"))) {

nlmixr2_m3 %>%
  backfill_derived() %>%
  list_vars()

derive_prm(nlmixr2_m3)


# If param has no vars, .prm should be set
pheno_base %>%
  backfill_derived(
    .prm = c(CL,V)
  ) %>%
  list_vars()
}
