Subject: A. Mani : Avoiding loops
Hello,
I want to avoid loops in the following situation. There is a 5-col
dataframe with col headers alone. two of the columns are non-numeric. The
problem is to calculate statistics(scores) for each element of one column.
The functions depend on matching in the other non-numeric column.
A B C E F
1 2 X Y 1
2 3 G L 1
3 1 G L 5
and so on ...30000+ entries.
I need scores for col E entries which depend on conditional implications.
Thanks,
A. Mani
