expand_addl_ii: Expand rows in case ADDL and II variables are present

In amp.dm: Data Management Tools for Pharmacometrics

Expand rows in case ADDL and II variables are present

Description

This function expands ADDL and II records. This is done by placing each ADDL record on a separate line. This is convenient in case of individual dose calculations

Usage

expand_addl_ii(data, evid = NULL, del_iiaddl = TRUE)

Arguments

data	data frame to perform the expansion on
evid	character identifying the event ID (EVID) within the data frame This is used to distinguish observations from dosing records, e.g. 0 for observations
del_iiaddl	logical identifying if the ADDL and II variables can be deleted from output

Details

The function expects that certain variables are present in the data (at least ID, TIME, ADDL and II)

Value

a data frame with expanded dose records

Examples

dfrm <- data.frame(ID=c(1,1), TIME=c(0,12),II=c(12,0),ADDL=c(5,0),AMT=c(10,0),EVID=c(1,0))
expand_addl_ii(dfrm,evid="EVID")
