and you have still not read the posting guide?
It asks you to "provide commented, minimal, self-contained, reproducible
code" which also means that you need to tell which packages you are using.
I get, e.g.:
> cuminc(ftime,fstatus,group)
Error: could not find function "cuminc"
> ftime
Error: object 'ftime' not found
> fstatus
Error: object 'fstatus' not found
> group
Error: object 'group' not found
