I've been trying to aggregate my current data set into a panel format. Currently the data is a cross section of people and I'd like to aggregate by state. For example, there are multiple observations for Maine in 2013 and I'd like to condense the data so that is its own row. Some variables that are individual specific would be dropped but the state variables toward the end would be kept. Any help would be much appreciated!

Note that when I try running ~dataex~ I receive an error message as I have too many variables. Is there a way I can get around that to share my data?
