Hi everyone, I have the following data Year Month Day Hour Var 2011 1 1 1 A 2011 1 1 1 B 2011 1 1 1 C 2011 1 1 1 D 2011 1 1 1 E 2011 1 1 2 A 2011 1 1 2 B 2011 1 1 2 D 2011 1 1 3 C 2011 1 1 3 D 2011 1 1 3 E 2011 1 1 4 A 2011 1 1 4 B 2011 1 1 4 D 2011 1 1 4 E where Var, if complete, should have data A, B, C, D, E at each hour. However at present, only Hour 1 has the full set of data. Hour 2 has only A, B, D. Hour 3 has only C, D, E. Etc. I would like to add all the missing data in Var at each Hour for the whole Year 2011 (amd other Years too). Is there a simple step for this process? Thanks so much for your help!
