Dear all,
Suppose I have the following dataset
I'd like to create a list of IDs based on var1 and var2. In particular, I'd like to get the same ID when the observations in var1 and var2 are swapped. For example, var1=3 and var2=4 should have the same ID as where var1=4 and var2=3.
I have tried
but it doesn't not give me exactly what I'm looking for.
Could anyone please help me with this?
Thank you very much for your help,
Vinh
