This would, I guess, be easier to answer if you gave examples of
the data structure you are using or intending to use.
What are your variables? What defines your observations?
However, observations can be identified as agreeing on
two variables by something like
... if var1 == "yes" & var2 == "yes"
... if var1 == 1 & var2 == 1
