Your life may be unneccessarily harsh if you stick to string as the type for
"id1". If you

destring, replace

Stata checks whether any vars in your dataset can be safely turned into

Betreff: st: dyadic dataset w string id
Dear all,
I have a variable id1 that is a 4-character string specific to each country;
var1 is numeric and d1 is binary. I need to construct a dyadic dataset that
will include all dyadic combinations of this variable.
If the original dataset looks like this:
Year country id1
var1 d1
2008 Greece 0214
3000 1
2008 Greece 0543
6000 0
2008 Greece 1234
3000 1
Š
What I am looking for would be:
Year country id1
id2 d1 d2
2008 Greece 0214
0543 1 0
2008 Greece 0543
1234 0 1
2008 Greece 1234
0214 1 1
Thank you kindly for your help.
