Hi,

Could you help me how I can browse only those observations containing similar values at least in two variables ? For example if I have three variables:

Obs var1 var2 var3
1 3 8 6
2 4 8 4
3 6 7 9
4 1 1 1
5 3 8 8


In this case, I want to identify those observations with at least two similar values in a row. that is Obs 2, 4 and 5
