Is this a for a homework assignment? We try to avoid doing others' homework
on this list.

To learn more about how to do simulations in R, search on "how to simulate
data in R" or similar. This brought up many tutorials that should be
helpful.

If this is not homework, maybe someone else can make sense of your query
and can help. I could not.
