Right. This is what I get with the command that you suggested me:
egen group = group(iso1 iso2), label
. tsset group year
panel variable: group (unbalanced)
time variable: year, 1950 to 2006, but with gaps
delta: 1 unit
but when I say it does not work I mean that basically stata does not
make any change in the dataset.
