carlo, they don't, one variable is an "index of participation" that runs from 0 to 1, the other is the "intensity of trust" that also runs from 0 to 1 so i have only one row of data per subject. i want to run

trust <- participation ....
thanks everybody for the help, maarten i will check out your programs.
