Hi all,
I'm struggling to grasp in a string all the values of a dicrete variable. Any hint?
Best,
Artur

Things must look like this:

string col_title = ""
discrete groups
matrix val = values(groups)
loop i = 1..rows(val) --quiet
    col_title += val(i)       # of course, it doesn't work
    col_title += " "
endloop
