Subject   st: Finding individuals that had the same ranking across choices.

My apologies.... here is an example of the data. Below I show two
individuals (id 1 and id 2). The first individual always has the same
ranking across the 8 choices.... 3, 2, 1.
The second individual has different choices for different questions.
I want to generate an indicator for individuals who, like id 1 in this
case, always have the same ranking across choices.
I hope this makes more sense?
