Thanks for your reply!

Doing this, I think (!) I can compare the the x value of type 1 with
every other x value of type 2. This will give me a hint about how
often a certain value x of type 1 is higher/lower/ or equal compared
to all other values in the sample. Vice versa for type 2. Due to my
limited programming capabilities I thought this would be an easy way.
Do you think there is a better way? (Certaintly there is. =) )

Toby.
