I am trying to just get some simple means of indicator variables and store them to create a new data frame:

Code:
sysuse nlsw88, clear
mean south
eststo
mean smsa
eststo
mean union
eststo

esttab using example.csv
How would I get the inverse of that? So for -union-, the percent of non-missing who are in a union is 20.53, and percent not in a union are 63.09. With the code I have above, it will store and produce the 20.53%. Is there a way to get the 63.09 figure without creating a new reverse-coded variable?
