Allin, I was playing with the square() function in the list context. It would be very useful if one could specify the equivalent of the --cross option in the function, as in
list foo = x1 x2 x3 list foosq = square(foo,1) # x-products as opposed to list foo = x1 x2 x3 list foosq = square(foo,0) # no x-products I've been trying to find the place in the source where to make some changes, but I gave up after the umpteenth Alt-. Any advice? Riccardo `Jack' Lucchetti Dipartimento di Economia Università di Ancona jack(a)dea.unian.it http://www.econ.unian.it/lucchetti
