Exactly! Thanks, Duncan.
Let me re-phrase me question like this:
1) X_i values are independent Gammas, with the shape 0.067 and scale 0.008
2) Min(X)=1 and Max(X)=85
3) SUM(X)=2000
4) Do I also have to define the number of draws? if yes, it could be 250.
Based on these restrictions, I want to

You might want to check that your parameterization in in agreement
Thanks.
I tried the rgamma function too. But I'm still wondering how I can set the
min, max, and sum of the variates created by the random draws. Anyone has a
clue? Thanks.

By the way, maybe the number of groups can be determined endogenously. It
will be better if I do not have to set the total number of groups
exogenously.
Thanks
