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.
