Here is what I tried to do:
I had the data originally like this:
1960.01
1960.02
So:
generate year = real(substr(date,1,4))
generate month = real(substr(date,6,2))
generate paneldate = ym(year,month)
format paneldate %tm
When I tried to:
tsset c_code (my panel data operator) paneldate, monthly
It claims error 451, repeated time values within panel.
I apologize for not making it clear. Maybe you can tell me where I'm going
wrong with this info.
