Reproducible Example

adae <- tibble::tribble(
  ~USUBJID, ~AESTDTC, ~AENDTC, ~ASTDT, ~AENDT, ~AEDECOD,
  "P01", "2022-01-10", "2022-01-12", ymd("2022-01-10"), ymd("2022-01-12"), "Nausea",
  "P02", "2022-01-31", "2022-01-31",ymd("2022-01-31"), ymd("2022-01-31"), "Vomitting",
  "P02", "2022-02-02", "2022-02-04", ymd("2022-02-02"), ymd("2022-02-04"), "Vomitting"
)

adex <- tibble::tribble(
  ~USUBJID, ~EXTRT, ~EXDOSFRQ, ~EXSTDTC, ~EXENDTC, ~ASTDT, ~AENDT,
  "P01", "Drug A", "QD", "2022-01-09", "2022-01-12", ymd("2022-01-09"), ymd("2022-01-12"),
  "P02", "Drug A", "QD", "2022-02-01", "2022-02-04", ymd("2022-02-01"), ymd("2022-02-04")
)

(adex_single <- create_single_dose_dataset(adex))

derive_vars_last_dose(
  adae,
  adex_single,
  by_vars = vars(USUBJID),
  dose_date = EXSTDT,
  analysis_date = AESTDTC,
  new_vars = vars(EXSTDT = ASTDT)
)

Error in `assert_data_frame()`:
! Required variable `EXSTDT` is missing
Run `rlang::last_error()` to see where the error occurred.

[thomas-neitmann]

Upon further inspection the error is not related to the renaming itsef. That works as expected. However, if a renamed variable is specified in dose_date as per the example above then the assert_data_frame() call errors because that renames variable is not yet in the dataset.
