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

Best,
