really thanks !
id filterCriteria ratingOfSatisfaction ProductType
1 60 A
1 40 B
3 20 A
5 40 A
5 100 B
5 80 C
I know that's no a perfect database model .
But the dataset is much longer and now i have got a problem
i.e filter the ratingOfSatisfaction with gender!
Is there a possibilty to write a function in the really flexible R , which
autocount (copy the rows under the first row per ID for the filterCriteria)
until a new Id starts and again ....
advance & regards,Christian
