Global sum of a column
Hi,
I am very disappointed with the way of calculation the simple global sum in RapidMiner. I think if you are unable to make this easy - there is no sense to continue with more complicated things.
In particular, I just need to get a % of an amount for each row from the total sum of a column. This procedure takes normally just seconds in Excel.
Nor Aggregate, neither Pivot could help me - as I don't need "Count", I need a "Total Sum".
