st: Conditional Variable means to new observation

Hi,
I am looking to take a conditional mean (or sum) of a variable and include it as a new observation.
For instance, I have data with several county indicators horizontally and county ids vertically. I would like to take the mean growth rate (a variable) for only those counties that are Large (LgMdSm==2) and create a new observation that contains that value under the variable growth rate.
In other instances, I would like to take the sum.
I feel like this is probably a simple operation, but couldn't find any immediate help through a google search.
Any help would be appreciated, thank you,
