Hi Kris,
You just need to understand the mathematics of the incomplete gamma function
and the various relationships it has. The answers from both Mathematica and R
are correct, except that they are giving you different estimated quantities. It
depends on the way the gamma function is written. For instance in R to get the
equivalent result from mathematica you should do the following
answer <- gamma(9) - Igamma(9,11.1). This will give you the incomplete gamma
for (9,11.1) as given by Mathematica.
You can read more about the model and am sure you will figure it out.

Anup
