Note that this works:

   rxode2et::et(c(0,1), cmt=Cc)
#> ── EventTable with 2 records ──
#> 0 dosing records (see x$get.dosing(); add with add.dosing or et)
#> 2 observation times (see x$get.sampling(); add with add.sampling or et)
#> ── First part of x: ──
#> # A tibble: 2 × 3
#>    time cmt   evid         
#>   <dbl> <chr> <evid>       
#> 1     0 Cc    0:Observation
#> 2     1 Cc    0:Observation
