I am trying to use a calculated column to sum the values per a text category but I keep getting "NaN" as the result. Can you tell what the problem is?
Attached is an example table...
The formula that gives NAN is:
cumulativeSumInCategory(plateID,"penalties")
I am expecting a new column that has the sum 14 for the first 3 entries and 7 for the second 3 entries, (same number for each of 3 rows).
BTW, I have no success with frequencyInCategory either. Can the frequency count unique text strings (eg. SMILES) as well as numbers?
Thanks,
Greg

Dear Greg,
the computation fails because the instruction contains an error in the syntax. In your example, plateID and penalties are not variables, but label-like column headers. For this reason both are to be enclosed in quotes. To enable a computation, the formula thus shall be written as
cumulativeSumInCategory("plateID", "penalties")
Your description of the anticipated results differs from this, though. It is better described by the formula categorySum("plateID", "penalties")
