Hi,
I have two variables, Partner1 and Partner2, which contain unique passport numbers in string format. An example:
Over here, we have 6 observations. However, we see that E100 and E101 are "repeated" between the two variables. Is there a way to count the number of repeated string variables in two variables? Thank you.
