Dear all, For the past three hours I have tried simplify a data frame. I would be really happy if someone could help solving this, I'm sure simple, problem.
I want to "aggregate" the data frame: ObjektID BalteNummer Baltessegment S.13 S.13.1 S.13.1.2 S.13 S.13.1 S.13.1.3 S.13 S.13.2 S.13.2.1 S.13 S.13.2 S.13.2.2 S.13 S.13.2 S.13.2.3 S.13 S.13.3 S.13.3.6 S.13 S.13.3 S.13.3.7 S.13 S.13.3 S.13.3.8 S.13 S.13.3 S.13.3.9 so that the results look likte this: ObjektID BalteNummer S.13 S.13.1 S.13 S.13.2 S.13 S.13.3 There are in fact many ObjektID. Thanks in advance!
