Could someone please help me - it is probably quite simple, but I cannot work this out...
My df consists of 3 column of either Low, Medium or High.
I would like a new column summing up the first 3 column:
Low: if obs in column 1-3 are all low
Medium: If 1 or more of the obs in column 1-3 are medium (or less)
High: If at least 1 of the obs in column 1-3 are high.
I have tried this, but the conditions never accepts "High" ...?
