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
Value
a data frame with expanded dose records
Details
The function expects that certain variables are present in the data (at least ID, TIME, ADDL and II)

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")
#> ID TIME AMT EVID
#> 1 1 0 10 1
#> 2 1 12 10 1
#> 3 1 12 0 0
#> 4 1 24 10 1
#> 5 1 36 10 1
#> 6 1 48 10 1
#> 7 1 60 10 1
