Special DM Cut to reset Death variable information past cut date

Source: R/special_dm_cut.R
special_dm_cut.Rd

Applies patient cut if patient not in source DCUT, as well as clearing death information within DM if death occurred after datacut date

Usage

special_dm_cut(dataset_dm, dataset_cut, cut_var = DCUTDTM)

Arguments

dataset_dm

Input DM SDTMv dataset

dataset_cut

Input datacut dataset

cut_var

Datacut date variable found in the dataset_cut dataset, default is DCUTDTM

Value

Input dataset plus a flag DCUT_TEMP_REMOVE to indicate which observations would be dropped when a datacut is applied, and a flag DCUT_TEMP_DTHCHANGE to indicate which observations have death occurring after data cut date for clearing
