Hello,
I disagree with the way you've sorted the matrix, like this all A's
become first, then B's, etc, irrespective of the respondents. Each row
is a respondent, and the rows should be kept intact, but with a
different ordering. To this effect, use order():
z - y[order(y[,1], y[,2],

are valid reasons to use -, but the people who want to use it practically
never have them.
Just return a list of the items you want to return from within the function.
