   the second step in my exercice is to calculate the sum of the amout for each
   class et not the frequency
   i have this vector
   x           y
   1          100
   2          1500
   3          3250
   4          6250
   5          2000
   6           450
   i want to use the function table and cat to calculate the sum of the amount
   in each class [0-1000], [1000-3000],[> 3000]
   You want to use cut, not cat.  Take a look at the examples on the cut help
   page - they will help you.
