How do I flip rows and columns using tabout?

[Tommie Thompson]

I'm using the code:

tabout city using table.tex, ///
c(mean age mean gender), f(1) sum

This produces a table where each city is in the row, and "age" and "gender" as column headers. The cells display the mean "age" and "gender" for each city. I want to average out a lot more variables by city, and it would be nicer the cities were the column headers. Is there a way to do this? I'm specifically looking for a tabout solution. .Thanks
