Source: R/derive_vars_transposed.R
derive_vars_atc.Rd

Add Anatomical Therapeutic Chemical class variables from FACM to ADCM

Usage

derive_vars_atc(
  dataset,
  dataset_facm,
  by_vars = exprs(USUBJID, CMREFID = FAREFID),
  value_var = FASTRESC
)

Arguments

dataset

Input dataset

The variables specified by the by_vars parameter are required

dataset_facm

FACM dataset

The variables specified by the by_vars and value_var parameters, FAGRPID and FATESTCD are required

by_vars

Keys used to merge dataset_facm with dataset

Permitted Values: list of variables

value_var

The variable of dataset_facm containing the values of the transposed variables

Default: FASTRESC

Value

The input dataset with ATC variables added
