How can I have the list of the countries in a panel data?

[Ana Vasconcelos]

Hello,

I have a panel data for multiples countries at a quarterly frequency. I would like to have a list of the countries that I have in the dataset.
Can someone help me with the code to know the list of all the countries in the dataset?
Thank you in advance.

It depends on what kind of "list" you want. If you want to see a list in the Results window, -levelsof country- (where country is the name of your variable) will do it. If you want to put that list into a local macro so that you can use it later for some purpose, -levelsof country, local(countries)- will do that.

As tabulate evidently did not spring to mind for this purpose, it's worth introducing it to you as one of the basic commands.
