Details

If no obj argument is provided, an empty, minimal nif object will be generated. If a data frame is provided for obj, it is converted into a nif object. Minimally expected fields are ID, TIME, AMT, CMT, EVID and DV. If ID is missing but USUBJID is available, ID will be derived.

If the input is a sdtm object, a pharmacokinetic nif object is automatically generated. Analyte mapping formulae can be supplied as the ... argument. For details, see nif_auto().
